This user generated textual content is an important source of information to make sound decisions by the organizations and the government. The textual information can be categorized into two types: facts and opinions. Subjectivity analysis is the automatic extraction...
To check the consistency between requirements specification documents and regulations by using a model checking technique, requirements analysts generate inputs to the model checker, i.e., state transition machines from the documents and logical formulas from the regulatory statements to be verified as properties. During these generation processes, to make the logical formulas semantically correspond...
Text clustering is important in many application of information retrieval. This paper presents a study of clustering short texts in Bahasa Indonesia using semantic similarity approach where dictionary of synonyms and hyponyms is used to get information on word relatedness. We compare sentence similarity calculations based on lexical matching and word similarity. More than 250 sentences are involved...
We describe a preliminary project of extracting information from an extant dictionary of historical biographies, the "Dicionário Histórico-Biográfico Brasileiro" (the Brazilian Historical and Biographical Dictionary, shortened as DHBB), a longstanding project at the 'Centro de Pesquisa e Documentação de História Contemporânea do Brasil' (CPDOC) of the Fundação Getulio Vargas (FGV). For information...
Schema matching is a fundamental process in many database applications and its quality impacts the performance of such applications. However, finding semantic similarities among schema is a challenging issue in developing full automatic schema matching of distributed heterogeneous autonomous database. Lexical ambiguity is a pervasive phenomenon among these database schemas that prevent fully automatically...
A pilot study was conducted to test the ability of semantic web tools to design the Nubian Ontology for Nubba civilization. An important objective of the pilot study was to investigate the capability of the tools which help in developing semantic web services such as multilingual Dictionary and information retrieval (IR) services to design Nubian Ontology. TobBraid Composer was used as a tool in this...
The phrase networks of Chinese show small world, scale-free and disassortative mixing features in our previous paper. Here semantical relationships are considered to explain the small world feature. Then we simulate the formation of Chinese phrases using weighted graph theory. The weighted graph model generates power-law distributions and disassortative mixing as the empirical networks, which effectively...
The lack of accuracy is the main issue in language service research. One reason is the negligence of accommodating users and their cultures in discovering, composing, and organizing services. On the other hand, a community behavior is mostly mirrored in jargons, common sentences, mottos and so forth. Moreover, culture is inseparable to its contents. Most culture disputes are due to cultural contents...
Chinese Scientific & Technical Vocabulary System (CSTVS) is a kind of knowledge organization systems for Chinese SCIENTIFIC & TECHNICAL information resources management and deep knowledge services that proposed by us. Now we provides the CSTVS as free semantic resources for research and education users all over the world. In this paper, knowledge infrastructure and related content computing...
