API usability is a crucial issue in software development. One bottleneck of API usability is insufficient documentation. This study empirically confirmed the inequality of crowdsourced API documentation, which is one of the main sources of API documentation. To manage the inequality, a method for documentation reuse is proposed based on the nature of object-oriented programming language, inheritance. A case study was conducted in Stackoverflow, which is a widely used Q&A site, to study the feasibility of the documentation reuse. Results of the case study indicate that documentation reuse is feasible in improving both the coverage and quality of crowdsourced API documentations.
Semantic Web enables new accessing and managing methods of Web resources. The realization of SemanticWeb is based on the availability of rich semantic infrastructure. Activities of building semantic infrastructure are usually collaborative and infrequent. Low coverage to personal interests of semantic infrastructure prevents developers from building personalized Semantic Web applications. In contrast to activities of building semantic infrastructure, press clipping or Web contents bookmarking are common events in our daily lives. In addition to the relatively higher frequency, press clipping and Web contents bookmarking clearly reflect personal interests, which is a clearer goal for accumulating personalized semantic infrastructure. In this paper, an interest-driven development method (IDD) is used to solve the availability problem of semantic infrastructure. An architecture, called IDEA, is proposed to assist the interest-driven development and evolution of personalized semantic infrastructure through clipping Internet media of personal interests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
