Chapter 12: Web Usage Mining - DePaul University

Web usage mining refers to the automatic discovery and analysis of patterns in clickstream and associated data collected or generated as a re-sult of user interactions with Web resources on one or more Web sites [114, 505, 387]. The goal is to capture, model, and analyze the behavioral patterns and profiles of users interacting with a Web site.

Knowledge discovery using pattern taxonomy model in text .

In the last decade, many data mining techniques have been proposed for fulfilling various knowledge discovery tasks in order to achieve the goal of retrieving useful information for users. Various types of patterns can then be generated using these techniques, such as sequential patterns, frequent itemsets, and closed and maximum patterns. However, how to effectively exploit the discovered .

Effective Pattern Discovery for Text Mining - IEEE .

Effective Pattern Discovery for Text Mining Abstract: Many data mining techniques have been proposed for mining useful patterns in text documents. However, how to effectively use and update discovered patterns is still an open research issue, especially in the domain of text mining.

Integrating probabilistic extraction models and data .

Additionally, there may exist many interesting, unknown relational patterns that both improve extraction performance and provide insight into text. We describe a probabilistic extraction model that provides mutual benefits to both "top-down" relational pattern discovery and "bottom-up" relation extraction.

Text mining - Wikipedia

According to Hotho et al. (2005) we can differ three different perspectives of text mining, namely text mining as information extraction, text mining as text data mining, and text mining as KDD (Knowledge Discovery in Databases) process. Text mining is "the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources."

Applications for Pattern Discovery Using Sequential Data .

Sequential pattern mining methods have been found to be applicable in a large number of domains. Sequential data is omnipresent. Sequential pattern mining methods have been used to analyze this data and identify patterns. Such patterns have been used to implement efficient systems that can recommend based on previously observed patterns, help in making predictions, […]

Introduction Text Mining is a Discovery Text Mining is also referred as Text Data Mining (TDM) and Knowledge Discovery in Textual Database (KDT). Text Mining is used to extract relevant information or knowledge or pattern from different sources that are in unstructured or semi-structured form.

A Pattern Discovery Model for Effective Text Mining .

In this paper, we propose a novel pattern discovery approach for text mining. This approach first discovers closed sequential patterns in text documents for identifying the most informative contents of the documents and then utilise the identified contents to extract useful features for text mining.

to discover useful patterns. Text mining is the task of extracting meaningful information from text, which has gained significant attentions in recent years. In this paper, we describe several of the most fundamental text mining tasks and techniques including text pre-processing, classification and clustering. Additionally, we

An XML-Based Definition of a Database for Knowledge Discovery

Examples of these applications are the market basket analysis, that extract patterns such as association rules between purchased items, sequential patterns (that extract temporal descriptions between observed events), classification, clustering and link analysis [13, 2] (that provide e.g., user profiles), text mining, graph mining, and so on .

Computing on Phenotypic Descriptions for Candidate Gene .

Many newly observed phenotypes are first described, then experimentally manipulated. These -based descriptions appear in both the literature and in community datastores. To standardize phenotypic descriptions and enable simple data aggregation and analysis, controlled vocabularies and specific data architectures have been developed. Such simplified descriptions have several advantages .

Text Mining and Web Mining | Business Intelligence

Text Mining Text Mining is the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources. A key element is the linking together of the extracted information together to form new facts or new hypotheses to be explored further by more conventional means of experimentation.

EBIC: an evolutionary-based parallel biclustering .

EBIC uses a different representation compared with other evolutionary-based biclustering methods (Ayadi et al., 2012; Divina and Aguilar-Ruiz, 2006; Mitra and Banka, 2006).Instead of modeling a bicluster as a tuple with a set of rows and a set of columns, biclusters in EBIC are represented by a series of column indices.

Applications of pattern discovery using sequential data mining

Sequential pattern mining methods have been found to be applicable in a large number of domains. Sequential data is omnipresent. Sequential pattern mining methods have been used to analyze this data and identify patterns.

Biomedical text mining and its applications in cancer research

Text mining, also referred as text data mining, is a branch of data mining that particularly deals with text. Discovering knowledge from biomedical text is a process with the aims to find answers for biomedical questions, such as identifying new drug targets or novel cancer diagnostic biomarkers.

Pattern Mining for Extraction of mentions of Adverse Drug .

We have presented a new method for using association rules for colloquial text mining. We applied our method on user comments to find mentions of adverse reactions to drugs by extracting frequent patterns. Since we are dealing with highly informal colloquial text, the idea of using extracted patterns might, at first, seem counter-intuitive.

A review on time series data mining - ScienceDirect

One of the major reasons for time series representation is to reduce the dimension (i.e. the number of data point) of the original data. The simplest method perhaps is sampling (Astrom, 1969).In this method, a rate of m/n is used, where m is the length of a time series P and n is the dimension after dimensionality reduction ().However, the sampling method has the drawback of distorting the .
