    Working with requirements means dealing with problems related to incomplete or faulty textual specifications. Specifications are created in various types and combinations such as models, drawings, and textual documents. The information gap between the specification and the implementation of any (software) system leads to delays, mistakes, and high costs due to problems in the production stages. Th...

  • Detecting Attempts at Humor in Multiparty Meetings

    Systems designed for the automatic summarization of meetings have considered the propositional content of contributions by each speaker, but not the explicit techniques that speakers use to downgrade the perceived seriousness of those contributions. We analyze one such technique, namely attempts at humor. We find that speech spent on attempts at humor is rare by time but that it correlates strongl... View full abstract»

  • Mapping Verbal Argument Preferences to Deverbals

    We describe an experiment mapping semantic role preferences for transitive verbs to their deverbal nominal forms. The preferences are learned by data mining large parsed corpora. Preferences are modeled for deverbal/argument pairs, falling back to a model for the deverbal alone when sufficient data is not available. Errors in role assignment are reduced by 35%.

    Semantic processing represents the new challenge for all applications that require text understanding, as for instance Q/A. In this paper we will highlight the need to couple statistical approaches with deep linguistic processing and will focus on ldquoimplicitrdquo or lexically unexpressed linguistic elements that are nonetheless necessary for a complete semantic interpretation of a text. We will... View full abstract»

    This paper presents the results of using statistical analysis and automatic text categorization to identify an author's age group based on the author's online chat posts. A naive Bayesian classifier and support vector machine (SVM) model were used. The SVM model experiments generated an f-score measurement of 0.996 on test data distinguishing teens from adults. We also introduce an alternative met... View full abstract»

  • Generalizing Latent Semantic Analysis

    Latent semantic analysis (LSA) is a vector space technique for representing word meaning. Traditionally, LSA consists of two steps, the formation of a word by document matrix followed by singular value decomposition of that matrix. However, the formation of the matrix according to the dimensions of words and documents is somewhat arbitrary. This paper attempts to reconceptualize LSA in more genera... View full abstract»

  • LAIR: A Language for Automated Semantics-Aware Text Sanitization Based on Frame Semantics

    Publication Year: 2009, Page(s):47 - 52
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (207 KB) | HTML iconHTML

    We present LAIR: A domain-specific language that enables users to specify actions to be taken upon meeting specific semantic frames in a text, in particular to rephrase and redact the textual content. While LAIR presupposes superficial knowledge of frames and frame semantics, it requires only limited prior programming experience. It neither contain scripting or I/O primitives, nor does it contain ... View full abstract»

    We discuss a probabilistic graphical model for recognizing patterns in texts. It is derived from the probability function for a sequence of categories given a sequence of symbols under two reasonable conditional independence assumptions and represented by a product of combinations of conditional and marginal probability functions. The novelty of our model is that it has a mathematical representati... View full abstract»

    This paper introduces a new metric for automatically evaluation summaries called ContextChain. Based on an in-depth analysis of the TAC 2008 update summarization results, we show that previous automatic metrics such as ROUGE-2 and BE cannot reliably predict strong performing systems. We introduce two new terms called Correlation Recall and Correlation Precision and discuss how they cast more light... View full abstract»

    A contextual analysis processing technique, consisting in determining the context understanding together with coherences in sentences, of concepts and phenomena related to each others, must be able to simultaneously interpret accurately a sequence of multiple semantic representations. A word frequently carries different meanings according to the context. For example, having a ldquobig heartrdquo i... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (177 KB) | HTML iconHTML

    In this paper an approach based on Wikipedia link structure for sense disambiguation is presented and evaluated. Wikipedia is used as a reference to obtain lexicographic relationships and in combination with statistical information extraction it is possible to deduce concepts related to the terms extracted from a corpus. In addition, since the corpus covers a representation of a part of the real w... View full abstract»

    This paper presents a new model of lexical-semantic representation of the lexicon which is intended for use in word sense disambiguation and semantic representation of text. It is usage-based, and part of it can be created automatically from an electronic dictionary. Although there remains more work to be done, the current model is provided with both syntactic and semantic contexts in which words ... View full abstract»

    This paper presents an approach for representing queries in natural language as semantic networks. The semantic representation is intended to facilitate the translation between natural language and database queries. A domain agnostic algorithm, based on shallow features, is used to map a sentence to a sub-network of concepts within a larger ontology. This work focuses on transportation information...

    This work identifies relevant songs from a user's personal music collection to accompany pictures of an event. The event's pictures are analyzed to extract aggregated semantic concepts in a variety of dimensions, including scene type, geospatial information, and event type, along with user-provided keywords. These semantic concepts are then used to form a search query against a song database based... View full abstract»

    This paper aims to provide a semantic Web based video search engine. Currently, we do not have scalable integration platforms to represent extracted features from videos, so that they could be indexed and searched. The task of indexing extracted features from videos is a difficult challenge, due to the diverse nature of the features and the temporal dimensions of videos. We present a semantic Web ...

    State-of-the-art systems for generic concept detection rely on low-level features, and in some cases additionally on features based on face detection, optical character recognition and/or speech recognition. In this paper, an approach for the task of semantic video retrieval is presented that systematically utilizes results of specialized object detectors. Using these object detectors trained on s...

    The organization and retrieval of images and videos is a problem for the typical consumer. A typical image collection includes many pictures of common activities that are not considered to be important by the user. These images inflate the number of assets in a collection to the point where it is difficult to find significant events when browsing. It is useful for the user to be able to browse an ...

    Based on contrastive experiments the following article presents a discussion on the difficulties of using state-of-the art speaker recognition methods under realistic car noise conditions and argues that, even though work has been done in this area, current approaches fail to address the main problems occurring in this task. The article also proposes a possible solution which opens new directions ... View full abstract»
