Methodology

There are so many factors could be used to evaluate a search engine, for example, user interface, user interaction, docs, performance and so on. In order to formalize these features, an evaluation methodology proposed by Li [1] and his colleges will be applied for Lenovo search engine. Based on the method, two major groups of evaluation parameters have been identified, Feature group and Performance group. Feature group consists of characteristics that enhance the usability and user-friendliness of the search engine. Performance group utilizes various metrics to examine the efficiency and the effectiveness of the search, such as recall and precision. The parameters in the Feature group are more static in nature since they represent facts and do not change often, while Performance parameters are dynamically measured and they depend on the particular search words used and the subjective ratings of the user. For this evaluation, we will focus on Feature group of Lenovo’s search engine.

Evaluation

Feature group can be further classified as six categories: Home Page Features, User Preferences, Search Options, Keyword Entry Options, Database and Result Features.
