Specifically, we leverage the use of figurative language (i.e., the choice of metaphors) in online text (e.g., news media, blogs) produced by distinct communities to obtain models of community worldviews that can be shown to be distinctly biased and thus different from other communities' models. We automatically construct metaphor-based community models for two distinct scenarios: debates on gun rights and marriage equality. We then conduct a series of experiments to validate the hypothesis that the metaphors found in each community's online language convey the bias in the community's worldview.", |

| "text": "Recent advances in machine learning, particularly deep learning, have led to successful exploitation of vast amounts of human-generated internet data and have produced remarkably accurate computational models of complex semantic and social phenomena in language, speech, vision, and other media, thus bringing us closer to the practical reality of artificial intelligence. These models are often considered objective and universal because the volume of data on which they are based is so vast that it is believed to be free of sampling limitations plaguing earlier research. And yet, the models that can be derived are only as good as the data from which they are built; the data, however vast, may still be biased. For one, people who post on the internet are not necessarily representative of the general population. Furthermore, society is composed of various communities and groups whose opinions and worldviews differ dramatically on a range of important issues. When data are oversampled from some sources over others (which can easily happen due to different rates of production), the resulting model is bound to be biased accordingly. This bias can lead to unwanted consequences, for example in government planning or resource allocation.", |

| "text": "The flip side of the data bias, however, is that each community produces a unique information footprint that may be used to understand how its members perceive the world. The objective of our project is to investigate whether online information generated by various communities can serve as raw data for developing reliable and accurate ethnographic models of these communities, thus augmenting costly and limitedscale field studies. Clearly, the methods of computational ethnography will be different from its traditional counterpart and will rely extensively on substantial volumes of largely undirected data, from which the critical information (e.g., relationships, opinions, conceptualizations) can be learned. One rich source of data is language, which serves as a communication vehicle, but also, as it evolves, encodes social, cultural, and often physical experiences of its user communities. These experiences are often vividly captured in the use of figurative language constructs, such as metaphors, that directly link abstract notions to collective physical experiences (Lakoff & Johnson, 1980; Thibodeau & Boroditsky, 2011) . This observation has been confirmed in earlier work that constructed metaphor repositories across language and cultural dimensions (Western/American, Latin American/Mexican, Eastern European/Russian, Middle Eastern/Persian) related to such notions as government, economic inequality, and democracy (e.g., Shutova, 2010; ;", |

| "text": "Our initial approach was to develop and evaluate ethnographic models of two U.S. communities: (1) a community whose members prefer individual oversight of guns and prioritize gun rights, which we refer to as INDO; and (2) another community whose members prefer government oversight of guns and prioritize gun control, which we refer to as GOVTO. Our research demonstrates that these two communities' cultural models differ fundamentally from one another in their representation and valuation of concepts related to the gun debate. These concepts include broad notions such as gun rights and gun control, as well as narrower issues such as the Second Amendment, school shootings, and assault weapons. Each community is defined by the set of valuations they assign to these concepts. In order to extract these valuations, we identify culturally biased correlations, expressed in the use of metaphorical language, between key gun-related concepts and more basic, concrete, and imageable source domains, such as war, barrier, disease, animals, natural force, water, and foodstuffs. Additionally, we capture the prevalent sentiment that members of each community apply when referring to these concepts, in both literal and metaphorical contexts. We leverage language data available through public online sources produced by the target communities. These sources include mainstream media as well as public community blogs, newsletters, and websites. Data are collected and processed automatically using simple internet crawlers and natural language processing software capable of analyzing sentences for grammatical components, sentiment, and presence of metaphors. The processed data are then deposited in searchable structured repositories that are unique to each community. We estimate that the amount of data required to support both confirmatory and exploratory studies is approximately 5 million words per community. In the initial feasibility demonstration stage of this project, we collected 6 million words for both the INDO and GOVTO community.", |

To do so, we identified appropriate media outlets that cater to the INDO and GOVTO communities, as follows: 1. Identification of spokespersons and spokesperson sites representing each community. This step typically requires input from a cultural/political expert; however, it may be approximated using distance calculation based on metaphor distribution. For the gun debate scenario, we leveraged known correlations of opinions with the liberal-conservative political spectrum. 2. Array sites along an opinion spectrum. In most cases, there will be a spectrum of opinions within each community. We were initially particularly interested in the most orthodox and extreme positions, because these provide the strongest contrast with other communities. This step is also assisted by input from cultural experts; however, it may be approximated by the Topical Positioning method (Lin et al., 2013) that tracks sentiment polarity in addition to metaphor choice.

The positions of various participants in the U.S. gun debate range on a scale from radically in favor of government oversight of gun ownership, through a more moderate position in favor of this oversight, to a moderate position against such oversight, ending in a radical position against government oversight. In the U.S., this range corresponds roughly to a spectrum of U.S. political thought, arrayed typically on a scale from the radical left through the center to the radical right.", |

| "text": "The process of identifying key concepts relevant to the case scenario has been fully automated. It proceeds in the following three steps: 1. Locate frequently occurring topics in text. The initial candidates are noun phrases, proper names (of locations, organizations, positions, events, and other phenomena, but less so of specific individuals). These are augmented with co-referential lexical items: pronouns, variants, and synonyms. The process of selection is quite robust but requires some rudimentary processing capability in the target language: part-of-speech tagging, basic anaphor resolution, and a lexicon/thesaurus. 2. Down-select frequent topics to a set of 20-30 concepts. The two key criteria are length and polarization. Topic length is measured by the number of references to the topic (either direct or indirect) that form \"chains\" across the \"utterances\" that are part of the scenariorelated debate. Topic polarization is measured by the proportion of polarized references to the topic, either positive or negative. For example, the terms gun rights and gun safety are both frequently used and polarized in the gun debate. 3. Select metaphorical targets. Although all topics selected in Step 2 are important to the scenario, only some of them are likely to be targets of metaphors. We determine this simply by probing metaphor extraction for each of the selected topics and then eliminating these that do not bring back a sufficient number of metaphors or where the metaphor-to-literal ratio is too low. For example, \"gun\" is mostly used literally and is a poor metaphorical target. We used a 2% cut-off threshold for productive targets (a typical metaphor to literal ratio is 8-10%).", |

The initial scenario involved two distinct views of gun rights versus gun control in the U.S. and developing ethnographic models of the communities representing these views. This initial scenario was partly based on the preliminary work conducted in the IARPA Metaphor program. The second scenario developed models for communities within the U.S. that hold different views on the topic of marriage equality, including same-sex marriage. Unlike the gun rights scenario that is essentially binary, the marriage equality topic produced multiple views, thus making the modeling task significantly harder. Nonetheless, we demonstrated that our approach can successfully support derivation of multi-faceted models. We summarize the first scenario only briefly; see Shaikh et al., 2015 for a complete description. The second scenario is described in more detail. Gun Rights Scenario. Within the U.S., a public debate is ongoing concerning the Constitutionally and socially appropriate management of gun ownership, between those favoring Federal Government oversight (GOVTO) and those favoring individual oversight (INDO). At their extremes, the two sides are far apart. They view the issue in different conceptual terms, the GOVTO side relying heavily on DISEASE related metaphors and the INDO side relying on WAR related metaphors. These views appear reasonably constant over the years, even as the volume of output from each side changes.", |

For example, the textual metaphor \"erosion of gun rights\" alludes a shared property between gun rights and a geological landmark, thus invoking \"Gun Rights is a Geological Landmark\" conceptual metaphor. We note that conceptual metaphors are often implied rather than directly stated.

All passages were processed by the software to determine whether a target term was used metaphorically or literally. In both cases, the semantic relation involving the target term was identified so that sentiment toward the target could be computed. For metaphorical cases, the relations were further classified into one of several dozen metaphorical source domains (see Table 1 ), such as War, Disease, or Barrier. The processed passages form the metaphor repository database, from which community models are derived. We also analyzed the distribution of metaphors with respect to the source domains. A source domain is a concrete semantic class to which the target is likened. The assignment of a metaphor to a source domain is determined by metaphorical relations that are applied to the target in a particular instance. For example, in \"the plague of gun violence\" the metaphorical relation is \"plague,\" which is a sub-concept of DISEASE (e.g., in Wordnet; Miller, 1995) . Therefore, this metaphor is classified as DISEASE metaphor -that is, \"gun violence\" is likened to disease. Table 1 shows a partial list of source domains we used, along with definitions and anchor terms that are representative members of each domain. The complete list of 67 source domains was compiled by the IARPA Metaphor Program. In Figure 1 , we present the top choices of source domains for metaphors associated with the target concepts, including gun control, gun rights, and gun violence. We note that DISEASE and CRIME dominate on the GOVTO side, while BARRIER and WAR explain nearly half of INDO metaphors. This analysis illustrates one type of strong bias that is found in the data and confirms some earlier findings (Shaikh et al., 2015) over new data.", |

| "text": "We applied our metaphor extraction system to the marriage equality data, initially concentrating on the three major stances noted above (i.e., the progressive, moderate, and traditional communities). We used the same list of source domains as with the gun debate scenario. Overall, we extracted 8305 metaphors including targets such as marriage equality, same-sex marriage, and gay rights. As expected, the selection of source domains was different than in the gun debate scenario, but again it showed marked contrast across the stances. Moreover, unlike in the gun debate scenario, we did not have an a priori classification of media sources as representing a particular stance. Instead, the set of all metaphors was split 3-ways using K-means clustering applied on the metaphor distribution statistics, taking into account the metaphor target, the metaphoric relation, the target role in the relation, and the source domain. Figure 2 shows near-perfect 3-way separation between sources representing progressive, moderate, and traditional views on marriage equality. A further attempt to separate the finer-grained seven stances described above was somewhat less successful, producing an Adjusted Rand Index (ARI) score of only 0.27, partly due to soft boundaries between some of the stances and insufficient data. We note that alternative approaches to obtaining automatic separation of stances based on topic and sentiment distribution did not come close to the result seen in Figure 2 . A doc2vec based method (Le & Mikolov, 2014) only achieved an ARI score of 0.17 on the 3-way split; an LDA-based approach (Blei et al, 2003) did only slightly better at 0.37.", |

| "text": "Figures 3 to 5 show the metaphor distribution across the three main stances in the marriage equality domain. The first analysis (Figure 3 , Table 2 ) shows metaphor distribution in language collected from progressive sources. The dominating metaphor is Forceful Extraction, which involves relations such as \"ban\" and \"prohibit.\" Other common metaphors, along with their frequent relations, are shown in Table 2 . Table 2 . Selected metaphoric relations for the most frequent source domains in the progressive stance. Figure 4 and Table 3 show the analysis of the moderate stance. The most frequent metaphor, representing about 23% of all collected examples, is Physical Location. This is followed by Medicine, which explains another 14% of the examples. This community had a relatively low output volume, producing a mere 5% of metaphors in our data set, with another 20% attributed to \"neutral\" sources. Figure 5 and Table 4 show the analysis of the traditional stance on marriage equality. Here the dominating metaphor is Medicine (20%). When coupled with a related and quite frequent metaphor of Addiction (5%), these two together form a hybrid \"bad medicine\" metaphor. Other frequent metaphors (Physical Location and Forceful Extraction) are also quite visible, which can be explained partly by the mixed content of the traditional stance cluster as well as frequent critical references to the progressive sources. At this time, we lack reliable means, beyond distribution frequency, of separating expressions that characterize one's own stance as compared to other people's stances. We note that sources representing traditional views account for only about 10% of extracted metaphors. ", |

The objective of this study was to confirm that the bias was captured in the metaphors used by each community and that this bias can be detected by human raters. We thus predicted that participants would be able to categorize the passages as representing the intended community viewpoints at rates above chance.
