Our corpus of descriptive text contains a significant number of long-distance pronominal references (8.4% of the total). In order to account for how these pronouns are interpreted, we re-examine Grosz and Sidner's theory of the attentional state, and in particular the use of the global focus to supplement centering theory.
Negation is present in all human languages and it is used to reverse the polarity of part of statements that are otherwise afﬁrmative by default. A negated statement often carries positive implicit meaning, but to pinpoint the positive part from the negative part is rather difﬁcult. This paper aims at thoroughly representing the semantics of negation by revealing implicit positive meaning. The proposed representation relies on focus of negation detection. For this, new annotation over PropBank and a learning algorithm are proposed. ...
This paper is concerned with the problem of question search. In question search, given a question as query, we are to return questions semantically equivalent or close to the queried question. In this paper, we propose to conduct question search by identifying question topic and question focus. More specifically, we first summarize questions in a data structure consisting of question topic and question focus. Then we model question topic and question focus in a language modeling framework for search.
In this paper, we propose a novel ranking framework – Co-Feedback Ranking (CoFRank), which allows two base rankers to supervise each other during the ranking process by providing their own ranking results as feedback to the other parties so as to boost the ranking performance. The mutual ranking refinement process continues until the two base rankers cannot learn from each other any more. The overall performance is improved by the enhancement of the base rankers through the mutual learning mechanism.
We present BAYE S UM (for “Bayesian summarization”), a model for sentence extraction in query-focused summarization. BAYE S UM leverages the common case in which multiple documents are relevant to a single query. Using these documents as reinforcement for query terms, BAYE S UM is not afﬂicted by the paucity of information in short queries. We show that approximate inference in BAYE S UM is possible on large data sets and results in a stateof-the-art summarization system.
We analyze the concept of focus in speech and the relationship between focus and speech acts for prosodic generation. We determine how the speaker’s utterances are inﬂuenced by speaker’s intention. The relationship between speech acts and focus information is used to deﬁne which parts of the sentence serve as the focus parts. We propose the Focus to Emphasize Tones (FET) structure to analyze the focus components. We also design the FET grammar to analyze the intonation patterns and produce tone marks as a result of our analysis.
The increasing complexity of summarization systems makes it difﬁcult to analyze exactly which modules make a difference in performance. We carried out a principled comparison between the two most commonly used schemes for assigning importance to words in the context of query focused multi-document summarization: raw frequency (word probability) and log-likelihood ratio.
We present an operable definition of focus which is argued to be of a cognito-pragmatic nature and explore how it is determined in discourse in a formalized manner. For this purpose, a file card model of discourse model and knowledge store is introduced enabling the decomposition and formal representation of its determination process as a programmable algorithm (FDA).
