It contains Swedish literary fiction, which has been manually annotated for cited materials, with a focus on dialogue. The annotation covers excerpts from eight Swedish novels written between 1879-1940, a period of modernization of the Swedish language. SL\u00e4NDa contains annotations for all cited materials that are separate from the main narrative, like quotations and signs. The main focus is on dialogue, for which we annotate speech segments, speech tags, and speakers. In this paper we describe the annotation protocol and procedure and show that we can reach a high inter-annotator agreement. In total, SL\u00e4NDa contains annotations of 44 chapters with over 220K tokens. The annotation identified 4,733 instances of cited material and 1,143 named speaker-speech mappings. The corpus is useful for developing computational tools for different types of analysis of literary narrative and speech. We perform a small pilot study where we show how our annotation can help in analyzing language change in Swedish. We find that a number of common function words have their modern version appear earlier in speech than in narrative.", |

| "text": "In literary studies, as in many other research fields, there has been a trend towards using computational methods. Traditionally, most research was based on close reading of books by researchers, whereas distant reading (Moretti, 2000) , the computational treatment of potentially large amounts of literary text, has become an important complement. While unsupervised methods, like topic modelling has been important in such studies, supervised models relying on annotated data are also often required. Annotated data is also useful for evaluation of proposed models, regardless of their type.", |

It is made up of eight Swedish literary novels from the late 19th and early 20th centuries, annotated mainly for different aspects of dialogue. The full annotation also contains other cited materials, like thoughts, signs and letters. The main motivation for including these categories as well, is to be able to identify the main narrative. Such a corpus can be useful for training and evaluating computational models, which in turn allows larger scale studies of cited materials, narrative, and dialogue in literature. Annotated literary corpora are quite rare, especially for Swedish, and as such we believe that SL\u00e4NDa could become a useful resource.", |

| "text": "We consider cited materials to be all parts that stands out from the main narrative of the novels. The most common type is direct speech from the different characters, forming dialogues, but it is not uncommon to have other types of cited material, such as thoughts of characters, signs, letters, and quotations. These parts of a novel are often different from the main narrative. The language can have differences to the main narrative, for instance, characters may have different speaking styles and dialects. It is important to be able to separate these parts for many types of studies, for instance focusing on the narrative when studying the overall plot of a novel, or for comparing the literary traditions of designing the characters' direct speech during different periods. In a linguistic perspective the corpus will enable a comparison between the narrative and the direct speech regarding for example oral style and colloquial expressions. A specific theory of interest to us is that language change happens earlier in dialogue than in the narrative (Engdahl, 1962) . The design of the lines and the speech tags is also closely related to the narrative technique in the novel -it may among other things throw light on the role of the narrator, see for example Allison (2018) , who studied Dickens' use of speech tags in a narrative perspective.", |

The speech tag is a description of the speaker, often in the form \"someone said\", but it can also contain further description e.g. of how something is said, or of events happening during the dialogue. Speech tags have also been called \"narrative constructions\" in characters' discourse (Ek and Wir\u00e9n, 2019) and \"narrator's report of speech\" (Semino and Short, 2004) . Speech tags form a part of the narrative; they are not part of characters' speech. An example speech segment from Sandel (p. 41) is shown in (1), 2 where there is a speech tag, containing an indirect reference to the speaker ('said a voice' where the context reveals that the voice belongs to the character Alice) as well as a description of its context ('between a couple of coughs').

| "text": "Even identifying speech segments might not be trivial, since different authors have different ways of marking them, see Section 3.2. Further, it can also be hard to distinguish where speech tags starts and ends. In this paper we will describe the design and creation of SL\u00e4NDa. In total, it contains annotations of 44 chapters with over 220K tokens. The annotation identified 4,733 instances of cited material and 1,143 named speaker-speech mappings. We also present a small pilot study where we investigate language change in literature, comparing speech segments to narrative, focusing on common function words, which have old-fashioned and modern variants. Ek et al. (2018) and Ek and Wir\u00e9n (2019) performed studies of dialogues in Swedish novels, where they tried to identify the speaker and addressee (Ek et al., 2018) 3 and speech tags (Ek and Wir\u00e9n, 2019) . In these papers they create classifiers to automatically identify these aspects. In order to do this, they annotated excerpts from four Swedish novels, partially overlapping with our selection. However, the main focus in these papers was on the technical aspects of the classifier for these tasks rather than on the annotations and the annotation process. Ek and Wir\u00e9n (2019) investigated how the distinction between speech tags and speech can be automatically predicted. They found that a reasonable baseline, that speech tags start with a speech verb and end with punctuation, does not perform well, with an F-score of only 47.9. They proposed a more advanced method based on logistic regression, which performed considerably better with an F-score of 80.8. These results show that distinguishing speech from speech tags in Swedish is far from trivial, and further motivates the annotation of more material that covers this distinction.", |

They studied the 3 Corpus available from https://github.com/ adamlek/dialogue-fiction structure and position of the speech tag in Swedish literary fiction, in a diachronic perspective. They compared Swedish novels from 1800-1900 to newer novels from 1976-1999. The speech tags were identified automatically using simple pattern matching based on quotation marks, possibly followed by a comma, followed by a verb in the present or past tense. This selection was noisy, and after a manual check, approximately 20% were excluded. The main result of the study was that the speech tag in the modern material is much less varied, the verb 'say' dominates, the tag is shorter and the final position dominates to a greater extent. A limitation of this study was that it only captured speech tags accompanying direct speech marked with quotation marks, which excluded a large number of works that marked speech in other ways.", |

In contrast to many other studies, they annotated speech tags in addition to speech segments. The corpus is manually annotated, and is based on a scale of speech and thought presentation categories, presented by Leech and Short (1981, p. 10) . The purpose of creating the corpus was to compare the variation in discourse structure between the three narrative genres. In the process of creating the corpus they used two main types of criteria, formal and structural as graphology on one hand, and more pragmatic, contextual criteria on the other hand. They also discussed embedded speech. The only discourse category they could capture solely with formal criteria was direct speech, as it was marked by citation marks. Unfortunately this is often not the case with direct speech in Swedish fiction, see Section 3.2.

| "text": "SL\u00e4NDa contains texts from eight novels by eight different Swedish authors, published between 1879 and 1940, see Table 1 for an overview. This period is regarded as a period of modernization for the Swedish language in syntax and vocabulary; thus we wanted a selection of texts where these changes might be illuminated. It has been suggested, but not thoroughly investigated, that literature, and especially literary dialogue, was driving this change (Engdahl, 1962) . We also wanted both male and female authors, as well as authors representing different literary traditions and using a mix of speech markers. For each novel we have selected between 2-10 chapters for annotation. We choose to annotate full chapters because we wanted clearly defined units of contiguous text. The chapters are sampled throughout the novels, and are not in contiguous order. Out of these, one annotated chapter per novel are held out as the test set of the corpus, to be used in future computational studies. For novels with at least eleven chapters, we choose chapter eleven for the test corpus, for the remaining novel by Sandel, we chose chapter two. The remaining chapters form the training part. We choose to annotate a higher number of chapters for three authors, one early author, one in the middle time span, and one of the later authors. The number of chapters annotated for each novel is shown in Table 1 . All together, SL\u00e4NDa contains 220,941 tokens, which is much larger than the 40,623 tokens used in Ek and Wir\u00e9n (2019) and nearly as large as Semino and Short (2004) .

These two variants of marking speech are common in Swedish, both historically and in modern texts. Two of the authors use more unusual variants. Levertin also uses a dash, but sometimes, adds it also before and after speech tags, which the other authors usually do not, see (3) for an example (Levertin, p. 134). Finally, Bergman mostly uses no marker at all, as in (4), Bergman p. 94. Speech tags can also precede the speech followed by a colon.

While We-bAnno could not easily handle our XML format, we could use its plain text line-oriented format. While this did not treat our XML-markup as XML, it was sufficient for our purpose, since the XML tags were not important for the annotation. Using this scheme, each paragraph was treated as a line, and could be annotated as a full chunk, if needed. For the output format, we use the native WebAnno format TSV 3. 6 It gives the full paragraphs in comments, followed by one word per line, containing the annotation in tab separated columns for different annotation levels, and information on sentence number, word number, and character offsets. Nested annotations are given in the same column, separated by a vertical bar. Each annotation is identified by a unique number. One issue with the TSV format is that it tokenizes XML markup as well as ellipses (. . . ). We retokenize this in a post-processing step. Figure 2 shows an example of our final annotation files, which can then be used for different types of further processing. Note the nested annotation, where the word Marianne is annotated both as a speaker and as part of the speech tag.", |

To do this, annotator 1 (A1) annotated two chapters in parallel with annotator 2 (A2), and two chapters in parallel with annotator 3 (A3). All chapters were from different authors, covering Benedictsson, Bergman, Boye and S\u00f6derberg. From this annotation we compare the top-level annotation between our main eight categories, and having no annotation, as shown in Table 2 .

Because many categories were rare in this material, we collapsed all categories except speech and speech tags into the other group. The only such cases were A1 having annotated 9 instances of embedded speech, and 2 thoughts, that A2 had not identified. Overall, though, there are no mismatches between the different categories. The only errors are cases where one annotator has identified the annotation, and the other annotator has not. In the overwhelming majority of cases, the annotators have marked the same spans, there are only a few cases of overlapping spans. We also calculated the Kappa statistic of overlap between the two pairs of annotators (Carletta, 1996) , for the identification of main category. The values were 0.72 for A1 vs A2 and 0.83 for A1 vs A3, which is normally interpreted as substantial and near perfect agreement.", |

One example is (6) from S\u00f6derberg (p. 191) , where it is hard to say if the speech is direct or indirect, and if it should be excluded, since we are not concerned with indirect speech. In most cases the difference between direct speech (DS) and indirect speech (IS) have been obvious but for the few borderline cases we have based our classification on a description presented in (Leech and Short, 1981, p. 256) . The primary difference between DS and IS is that DS is expected to report faithfully what was uttered and to report with the exact forms of the words. Thus IS is signalled by a lack of speech marks, by the form of a subordinate clause, by the change from first-and second pronouns to third-person, by change of the tense of the verb, from present to past tense, and by the change of deictic adverbs as here to there. The fact that there are no speech markers used, instead of S\u00f6derberg's standard citation marks, points to indirect speech while the remaining deictic adverb points to direct speech. The line contains no pronoun, and the tense of the verb would be possible in direct speech but prototypically changed in an indirect version: Henrik Rissler had said that there the time had stopped.

| "text": "The identification of speakers were more difficult, however. A1 and A2 agreed in the majority of cases, whereas A1 and A3 had more disagreements. The missing speakers is likely mainly due to inattention by the annotators. The mismatches seem to have many reasons. For A1 vs A3, all mismatches are due to that one of the annotators has not resolved a pronoun, which the other has done, which happens also for A1 vs A2 in 4 cases. A2 also has a larger tendency than A1 to mark the speaker as unknown. In only 4 cases, however, A1 and A2 disagree on the identity of the speaker, and in no case A1 and A3 disagree. Note that the number of speakers is smaller than the number of speech segments, because that contains both the start and continuation of speech segments. It seems like a common issue that all speakers are not identified; for instance, Elson et al. (2010) had the same issue when collecting their corpus. Even so, we would like to improve this part of the annotation in future work. In our final corpus, we only kept the annotations from A1, for the doubly annotated texts. Table 3 shows the size of the training and test parts of SL\u00e4NDa, in total and for each author. We think the size of the corpus is reasonably large, with over 155K words in the training part and 27K words in the test part. Words are defined as all tokens except punctuation marks. The total size of the corpus is over 183K words and 220K tokens. Table 4 shows the number of annotations across all authors in the training and test parts and Table 5 shows the number of annotations per author in the training corpus. Overall it can be seen that we have a reasonable number of annotations for the categories related to speech that is our main interest, both in total and per author. Embedded speech is relatively rare, though, and only occur in Bergman. 7 The other types of cited materials are quite rare, AS VB OL HS SL MS HB KB Type # W # W # W # W # W # W # W # W Speech 74 1486 891 17640 12 356 37 688 69 5138 74 2446 167 5417 33 1969 Speech tag 24 169 432 2216 12 65 41 232 53 373 46 316 148 756 27 164 Embedded 0 0 0 0 0 0 0 0 0 0 0 0 9 151 0 0 Thought 2 14 4 17 0 0 7 737 15 164 3 21 7 93 0 0 Sign 0 0 0 0 0 0 0 0 0 0 1 40 0 0 1 3 Letter 1 9 1 62 0 0 2 658 0 0 3 88 0 0 0 0 Quotation 6 101 2 31 0 0 0 0 0 0 2 67 1 9 0 0 Other 0 0 1 4 0 0 0 0 1 2 0 0 0 0 0 0 Table 5 : Statistics of how many annotations (#) and words (W) there are in the training part of the corpus for each category and author. Author given by initials, see Table 1 for full list often occurring in only one or a few authors. The possible exception is thoughts, which occurs for the majority of authors, but even they are rare compared to speech. As important as the annotated part is the unannotated parts, which consists only of the main narrative, since all cited materials is marked by annotations. The narrative is by far the largest part of SL\u00e4NDa. Table 4 also gives some additional details of speakers. As indicated by the inter-annotator agreement study, annotators have not always identified a speaker of a speech segment (Unmarked). They have also failed to resolve in total 52 cases of pronoun reference, which they were also supposed to do. There is also quite a high number of speech segments where the annotators were not able to resolve who the speaker was (Unknown). We still believe that the number of instances where the speaker is identified would be enough for training a classifier. 8 There are 68 unique identified speakers in our training data, and 36 in the test data. The speakers are identified by proper names, e.g. B\u00f6rje, Martin Birck, title and name, e.g. Fru Land\u00e9n ('Mrs Land\u00e9n), occupation e.g. sk\u00e5despelerskan ('the actress'), relationships e.g. modern ('the mother'), or other descriptions, typically noun phrases, e.g. den grekiske musikern ('the Greek musician').", |

The overall tendency is that there is a difference between the design of the narrative and of the direct speech: words, phrases and sentences are shorter in dialogue. The use of the function words shows the same tendency; the modern variants ska, inte, bara, ocks\u00e5 are more frequent in speech than in narrative. We can also see how the modern, colloquial forms as ska (instead of skall) initially are introduced in speech -in the earlier texts the authors either choose only skall (AS and OL) or use ska only in speech (VB, HS, SL and MS). The modern ska doesn't occur in narrative until our two latest texts, HB from 1924 and KB from 1940. In KB ska is the only variant -no skall. The variation between the two variants of the negation, the modern inte and the old-fashioned icke, is extra interesting as we can compare our results with a previous contemporary study on non fiction, Engdahl (1962) . He studied the linguistic changes in two Swedish magazines during 1878-1950 and showed that the older icke is in majority in all texts until 1925. From 1930 and on inte is the most frequent variant. The transition to the more modern variant is much earlier in our corpus: inte occurs in all texts except OL and gets majority quite early, from HS (1901) and on.

The main focus is on dialogue, for which we annotate speech segments, speech tags, and speakers. We show that we can perform this annotation with a high inter-annotator agreement for the identification of cited materials. The agreement for speakers is lower, but mainly due to missing annotations, rather than confusions between speakers.", |
