  • Retrieval of very large numbers of items in the Web of Science: an exercise to develop accurate search strategies
    arXiv: Digital Libraries, 2009
    Co-Authors: Ricardo Arencibia-jorge, Loet Leydesdorff, Zaida Chinchilla-rodríguez, Ronald Rousseau, Soren W. Paris

    Abstract:

    The current communication presents a simple exercise with the aim of solving a singular problem: the retrieval of extremely large amounts of items in the Web of Science interface. As it is known, Web of Science interface allows a user to obtain at most 100,000 items from a single query. But what about queries that achieve a result of more than 100,000 items? The exercise developed one possible way to achieve this objective. The case study is the retrieval of the entire scientific production from the United States in a specific year. Different sections of items were retrieved using the field Source of the database. Then, a simple Boolean Statement was created with the aim of eliminating overlapping and to improve the accuracy of the search strategy. The importance of team work in the development of advanced search strategies was noted.

  • Retrieval of very large numbers of items in the Web of Science: an exercise to develop accurate search strategies
    Profesional De La Informacion, 2009
    Co-Authors: Ricardo Arencibia-jorge, Loet Leydesdorff, Zaida Chinchilla-rodríguez, Ronald Rousseau, Soren W. Paris

    Abstract:

    The Web of Science interface counts at most 100,000 retrieved items from a single query. If the query results in a dataset containing more than 100,000 items the number of retrieved items is indicated as >100,000. The problem studied here is how to find the exact number of items in a query that leads to more than 100,000 items. One way to achieve this objective is presented. The retrieval of the entire scientific production from the United States in a specific year (2007) is counted and an advanced search strategy is designed. Different sections of items can be retrieved using the Source field of the database. A Boolean Statement was created with the aim of eliminating overlapped sections and improving the accuracy of this search strategy.
