Information extraction (IE) is a type of information retrieval (IR) whose goal is to automatically extract structured information from unstructured and/or semi-structured machine-readable documents.
Validation (效度)、Reliability (信度) and Verification (驗證) is very easy to get confused ...
What is the difference between "precise" and "accurate"? When we say the computation is accurate, is it a correct figure? Is it acceptable when the answer is precise?
Latent semantic analysis is a theory and method for extracting and representing the contextual-usage meaning of words by statistical computations applied to a large corpus of text (Landauer and Dumais, 1997). LSA is based on singular value decomposition (SVD), a mathematical matrix decomposition technique closely akin to factor analysis that is applicable to text corpora [...]
Here is a good article to explain VSM: http://www.miislita.com/information-retrieval-tutorial/term-vector-linear-algebra.pdf Vector space model (or term vector model) is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers. For example, these are documents d1, d2, d3, d4, d5 : d1= LSI tutorials and fast tracks d2= books on semantic analysis d3= learning latent [...]
Information retrieval = Information retrieval (IR) is the science of searching for documents, for information within documents, and for metadata about documents, as well as that of searching relational databases and the World Wide Web. There is overlap in the usage of the terms data retrieval, document retrieval, information retrieval, and text retrieval, but each [...]
Typographical term weighting is a method to weight special tags like bold or header tags in web pages. Typographical information includes the employment of different character fonts, character sizes and styles, the choice of line length, text alignment and the type-area within the paper format. Cutler, Shih and Meng (Using the structure of HTML documents [...]
A brand new year is coming to town. Wish all of you a wonderful year!
The concept of relevance in IR by Pai Borlund, 2003 This article introduces the concept of relevance as viewed and applied in the context of IR evaluation, by presenting an overview of the multidimensional and dynamic nature of the concept. The literature on relevance reveals how the relevance concept, especially in regard to the multidimensionality [...]
