  • This paper proposes a two-layered model of dialogue structure for task-oriented dialogues that processes contextual information and disambiguates speech acts. The final goal is to improve translation quality in a speech-to-speech translation system.

  • This paper presents a predicate-argument structure analysis that simultaneously conducts zero-anaphora resolution. By adding noun phrases as candidate arguments that are not only in the sentence of the target predicate but also outside of the sentence, our analyzer identifies arguments regardless of whether they appear in the sentence or not. Because we adopt discriminative models based on maximum entropy for argument identification, we can easily add new features. We add language model scores as well as contextual features.

  • This paper proposes a supervised learning method for detecting a semantic relation between a given pair of named entities, which may be located in different sentences. The method employs newly introduced contextual features based on centering theory as well as conventional syntactic and word-based features. These features are organized as a tree structure and are fed into a boosting-based classification algorithm. Experimental results show the proposed method outperformed prior methods, and increased precision and recall by 4.4% and 6.7%. ...

  • This paper proposes a principled approach for analysis of semantic relations between constituents in compound nouns based on lexical semantic structure. One of the difficulties of compound noun analysis is that the mechanisms governing the decision system of semantic relations and the representation method of semantic relations associated with lexical and contextual meaning are not obvious.

  • Our goal is to improve the contextual appropriateness of spoken output in a dialogue system. We explore the use of the information state to determine the information structure of system utterances. We concentrate on the realization of information structure by intonation. We present the results of evaluating the contextual appropriateness of varied system output produced with a text-to-speech synthesis system that supports intonation annotation.

  • We demonstrate the production of spoken output with contextually appropriate intonation in the information-state based dialogue system GoDiS. We exploit the context representation in the information state to determine the information structure of system utterances, which we use to control the intonation of synthesized spoken output.

  • It takes a clear and structured approach to grammar. Grammatical structures are introduced in context, with questions that encourage students to work out the rules for themselves. A comprehensive ‘Grammar section’ at the back of the Student’s Books provides a useful reference before, during or after the lesson. * A well-defined vocabulary syllabus concentrates on three key areas: learning new words in lexical sets; acquiring good habits for learning vocabulary; and developing vocabulary ‘systems’ such as sound and spelling relationships.

  • “If I didn’t have to go to meetings, I’d like my job a lot more.” It’s a remark I’ve heard from many of the leaders I’ve worked with over the years. I used to think that it was understandable—even humorous—but I’ve come to the conclusion that it’s actually a sad comment on the state of our business culture.

  • To better understand the international perspective of public policies for the elderly, in line with the parameters that serve as tendencies for national policies, one must contextualize international health conferences that had health promotion as their central topic. Since the Declaration of Alma-Ata, in 1978(5), it has been noted that measures and characteristics of health promotion imply a search for healthier life styles and active aging. Health promotion is seen as a process of community qualification, aiming to improve life and health conditions.

  • THE UNIVERSITY OF MICHIGAN undertook research, late in 1955, in the analysis of language structure for mechanical translation. Emphasis was placed on the use of the contextual structure of the sentence as a means of reducing ambiguity and on the formulation of a set of operative rules which an electronic computer could use for automatically translating Russian texts into English.

  • Multi-protein complexes are emerging as important entities of biological activity inside cells that serve to create func-tional diversity by contextual combination of gene products and, at the same time, organize the large number of different proteins into functional units. Many a time, when studying protein complexes rather than individual proteins, the bio-logical insight gained has been fundamental, particularly in cases in which proteins with no previous functional anno-tation couldbe placed intoa functional context derived from theirmolecular environment. ...

  • Turkish is an agglutinative language with complex morphological structures, therefore using only word forms is not enough for many computational tasks. In this paper we analyze the effect of morphology in a Named Entity Recognition system for Turkish. We start with the standard word-level representation and incrementally explore the effect of capturing syntactic and contextual properties of tokens. Furthermore, we also explore a new representation in which roots and morphological features are represented as separate tokens instead of representing only words as tokens. ...

  • We present a novel approach to parse web search queries for the purpose of automatic tagging of the queries. We will define a set of probabilistic context-free rules, which generates bags (i.e. multi-sets) of words. Using this new type of rule in combination with the traditional probabilistic phrase structure rules, we define a hybrid grammar, which treats each search query as a bag of chunks (i.e. phrases). A hybrid probabilistic parser is used to parse the queries.

  • This paper describes a hybrid model that combines a rule-based model with two statistical models for the task of POS guessing of Chinese unknown words. The rule-based model is sensitive to the type, length, and internal structure of unknown words, and the two statistical models utilize contextual information and the likelihood for a character to appear in a particular position of words of a particular length and POS category.

  • A "Front End" for a Computer-Based Glaucoma Consultation System is described. The system views a case as a description of a particular instance of a class of concepts called "structured objects" and builds up a representation of the instance from the sentences in the case. The information required by the consultation system is then extracted and passed on to the consultation system in the appropriately coded form.

  • Theodes of semantic interpretation which wish to capture as many generalizations as possible must face up to the manifoldly ambiguous and contextually dependent nature of word meaning? In this paper I present a two-level scheme of semantic interpretation in which the first level deals with the semantic consequences of'syntactic structure and the second with the choice of word meaning.

  • The basic premise of the KONTEXT model is that new concepts are communicated by using the mechanisms of text constitution. The text model used assumes that the information conveyed in a text and the information describing its contextual organization can be structured into five layers (sentence structure, information on thematic progression, referential structure, conceptual representation of the text and conceptual background knowledge).
