Text, being bland, is hardly a conducive and motivating medium for learning, especially when the reader does not have access to aids that would enable her to get over minor and not-so-minor roadblocks ranging from unknown vocabulary to unrecognized and forgotten names, hard-to-understand sentences, issues with the grammar and lack of or forgetting the prior context in a former session of reading. We aim to make reading an active and interactive experience by enabling the user to interact with the text in a variety of ways using anytime-anywhere contextually guided access to textual information.",

These annotated documents are then accessed via browser-based clients which essentially look like traditional e-book reading environments but with a much richer set of user accessible functionality. Thus our system can also be seen as a showcase application for demonstrating English NLP tools and resources. Our contribution is the integration of many publicly available tools and resources for English into a large-scale usable application implemented in a client-server software architecture structured around UIMA, along with work on development of some annotation components and/or combination of available ones.",

The Free-Text Project (Hamel and Girard, 2000) , developed a NLP-based CALL system for intermediate to advanced learners of French. The LISTEN project at CMU on the other hand, has aimed to tutor elementary school students in reading English text by using speech technology (Mostow and Aist, 2001) .",

In order to help the user to understand the grammatical relations in a sentence, our tool provides the reader with the ability to inquire about the grammatical role of a word within the sentence. The sentences in the documents are previously annotated with dependency relations and when a word is clicked, one of the other menu items the user is presented with is the option to view the grammatical role of the word (shown with the button \"Role\" in the figures) . When requested, we present the grammatical role in a user-friendly fashion by mapping dependency labels to more descriptive and meaningful labels as shown in Figure 6 .",

These questions are then ranked based on length, proximity and whether or not it or its answer involves another named entity, and a short list of questions are presented to the user. The user can then click on a question she is interested in, and immediately get the corresponding answer, which is also generated at annotation time in parallel with question generation.

Text simplification has been studied for both human text readers and programs that process text. We are specifically concerned with students who try to acquire English as a second language (Petersen, 2007) . Approaches for this target audience use simplification techniques as a preprocessing step to reduce complexity of sentence, mainly with respect to syntax (e.g., sentence decomposition on subordinate clause) and discourse structure (e.g., coreference resolution). We are developing a sentence simplification module that addresses both lexical and limited syntactic simplification problems to help improve reading skills of non-native English learners. Our current focus is on developing a lexical simplification module that can identify the \"difficult\" vocabulary items or idiomatic uses in text, and annotate with their simpler versions.",
