Streszczenie:

As a result of the rapid growth of the volume of electronic data, text compression and indexing techniques are receiving more and more attention. These two issues are usually treated as independent problems, but approaches of combining them have recently attracted the attention of researchers. In this thesis, we review and test some of the more effective and some of the more theoretically interesting techniques. Various compression and indexing techniques are presented, and we also present two compressed text indices. Based on these techniques, we implement an compressed full-text

Streszczenie:

The Vector Space Model (VSM) of text representation suffers a number of limitations for text classification. Firstly, the VSM is based on the Bag-Of-Words (BOW) assumption where terms from the indexing vocabulary are treated independently of one another. However, the expressiveness of natural language means that lexically different terms often have related or even identical meanings. Thus, failure to take into account the semantic relatedness between terms means that document similarity is not properly captured in the VSM. To address this problem, semantic indexing approaches have been propose

Streszczenie:

All practical text search systems use inverted indexes to quickly resolve user queries. Offline index construction algorithms, where queries are not accepted during construction, have been the subject of much prior research. As a result, current techniques can invert virtually unlimited amounts of text in limited main memory, making efficient use of both time and disk space. However, these algorithms assume that the collection does not change during the use of the index. This thesis examines the task of index maintenance, the problem of adapting an inverted index to reflect chang

The purpose of dissertation is to examine whether the understandings of subject indexing processes conducted by human indexers have a positive impact on the effectiveness of automatic subject term assignment through text categorization (TC).

Based on the premise that subject indexing approaches or conceptions with semantic sources are important for automatic subject term assignment through TC, this stud

Nucleic acids play vital roles in the cell by virtue of the information encoded into their nucleotide sequence and the folded structures they form. Given their propensity to alter their shape over time under changing environmental conditions, an RNA molecule will fold through a series of structures called a folding pathway. As this is a thermodynamically-driven probabilistic process, folding pathways tend to avoid high energy structures and those which do are said to have a low energy barrier. In the first part of this thesis, we study the problem of predicting low energy barrier folding pa

The large amounts of clinical data generated by electronic health record systems are an underutilized resource, which, if tapped, has enormous potential to improve health care. Since the majority of this data is in the form of unstructured text, which is challenging to analyze computationally, there is a need for sophisticated clinical language processing methods. Unsupervised methods that exploit statistical properties of the data are particularly valuable due to the limited availability of annotated corpora in the clinical domain.

Automatic indexing is the automatic creation of a text surrogate, normally keywords or phrases, to represent the original text. In the current English text retrieval systems, this process of content representation is accomplished by extracting words using spaces and punctuations as word delimiters. The same technique cannot easily be applied to Chinese texts which contain no obvious word boundaries; they appear to be a linear sequence of non-spaced or equally spaced ideographic characters and thenumber of characters in words varies.

Streszczenie:

The thesis describes the design and implementation of an application for processing electronic publications (collections of conference papers, comprehensive manuals, or even classical electronic books) in order to enrich their internal navigation by hyperlinks between their related parts, respectively producing as representative as possible summarizations of given length. Unlike similar applications summarizations can be based not only on the sentences, but on elements of other categories like paragraphs, sections and the like.The main emphasis was put on ease of use, platform independence, an

Streszczenie:

Current representation schemes for automatic text classification treat documents as syntactically unstructured collections of words (Bag-of-Words) or `concepts' (Bag-of-Concepts). Past attempts to encode syntactic structure have treated part-of-speech information as another word-like feature, but have been shown to be less effective than non-structural approaches. We propose a new representation scheme using Holographic Reduced Representations (HRRs) as a technique to encode both semantic and syntactic structure, though in very different ways. This method is unique in the literature in that

O crescimento massivo de dados multimédia na Internet e surgimento de novas plataformas de partilha criou grandes desafios para a recuperação de informação. As limitações de pesquisas com base em texto para este tipo de conteúdo proporcionaram o desenvolvimento de uma abordagem de recuperação de informação com base no conteúdo (CBIR) que recebeu atenção crescente nas últimas décadas. Tendo em conta as pesquisas realizadas nesta área, e sendo o foco desta investigação as imagens digitais, são explorados conceitos e técnicas associadas a esta abordagem por meio de um levantamento teórico
