This article presents Python codes that can be used to extract data from Securities and Exchange Commission (SEC) filings. The Python program web crawls to obtain URL paths for company filings of required reports, such as Form 10-K. The program then performs a textual analysis and counts the number of occurrences of words in the filing that…

Introduction: In the big data age, we have to deal with a tremendous amount of information, which can be collected from various types of sources. For information search systems such as Web search engines or online digital libraries, the collection of documents becomes larger and larger. For some queries, an information search system needs to…

The study of this dissertation provides a solution to a very specific problem instance in the area of data mining, data warehousing, and service-oriented architecture in publishing and newspaper industries. The research question focuses on the integration of data mining and data warehousing. The research problem focuses on the development of…

The techniques of search strategy design for substructure searches of the Wiswesser Line Notation (WLN) file are described in detail. The Index Chemicus Registry System'' was used. (13 references) (Author/SM)

The objectives of this paper are to describe the effect of using weighted index terms in a document retrieval system, and to evaluate retrieval performance when queries are expanded by terms occurring in clusters with the query terms. Three data collections, each indexed by several methods, two of which were studied and reported on in previous…

WISE-ONE is a bibliographic information retrieval system which is designed to perform keyword searches of such data-bases as the ERIC RESUMAST and the ERIC CIJEMAST. Produced as a result of the search are the ERIC citation numbers, titles, authors, and, in the case of the journal file, the journal citation. Because WISE-ONE allows for nesting of…

In Part I of the Session, Network members describe and compare their experiences in utilizing various aspects of the SUNY Retrieval System including "query" cycle, scan statements, author searches, and book files. Machine problems are discussed as well as options on charging for searches, how much information to retrieve, and serving…

The Educational Resources Information Center (ERIC) system's computerized data base was the focus of a three-hour tutorial session on search strategies. This document is the workshop manual used by the tutorial participants. The discussion of the input phase of a computer search covers identification of the user population, receiving the inquiry,…

The purpose of this guide is to give an up-to-date presentation of the information service offered by the documentation center at the Royal Institute of Technology (RIT) and to facilitate the utilization of the service. The guide gives a general account of the multidisciplinary computerized current awareness service (SDI) and a detailed…

Several problems of finding keys in directories are considered. Methods of searching ordered and unordered directories are analyzed. Searching on ranges of key values in also considered. Finally, design tradeoffs among the classes of directory and searching strategies are developed. (4 references) (Author/SJ)

Analysis of the distribution of relevant answers to 41 search profiles among the 80 subject sections of Chemical Abstracts" revealed that the average profile requires 10 CA-subject sections for adequate coverage. The average printing expense could be reduced 25 percent by searching the individual profiles in the appropriate subject sections. (5…

The Fort Detrick Information Retrieval System is a system of computer programs written in COBOL for a CDC 3150 to store and retrieve information about the scientific and technical reports and documents of the Fort Detrick Technical Library. The documents and reports have been abstracted and indexed. This abstract, the subject matter descriptors,…

A manual describing the RIC computer search program for retrieval of information from ERIC, CIJE, and other collections is presented. It is pointed out that two versions of this program have been developed. The first is for an IBM 360/370 computer. This version has been operational on a production basis for nearly a year. Four installations of…

The paper describes TSAR, a current awareness or SDI system which has been developed for processing MARC records in general, but is particularly concerned with the INSPEC service. Some statistics on the frequency of occurrence of words and comments on data compression conclude the paper. (7 references) (Author/SJ)

Describes the theoretical framework of a retrieval system that uses data structures called bitmaps to improve search algorithms for medium-sized systems. Information retrieval systems that contain the full text of the documents are discussed, and the use of inverted files such as concordances for small texts is explained. (24 references) (LRW)
