Yahoo! Developer Network Home

Yahoo! Developer Network Home 为大家提供了很多功能, 项目中需要寻找Related和spelling词汇, 这里使用了Yahoo! Search Web Services , 利用Yahoo提供的服务,可能轻松实现相关词汇检索和拼写检查.

Yahoo Search API针对不同的语言提供了不同的开发包, 使用起来很方便. 这里以java为例. 下载包中包含yahoo_search-2.0.1.jar 及javadoc. (正式部署应用程序的时候需要申请一个Application ID)

这里举例来请求RelatedSuggestion服务

java 代码

public static String[] searchRelatedSuggestion(String searchKey) {
    SearchClient client = new SearchClient(Application_ID);
    RelatedSuggestionRequest request = new RelatedSuggestionRequest(searchKey);

    RelatedSuggestionResults relatedSuggestionResults = null;
    try {
        relatedSuggestionResults = client.relatedSuggestion(request);
    } catch (Exception e) {
        e.printStackTrace();
        logger.error(e.getMessage());
    }

    if (relatedSuggestionResults == null) {
        return null;
    } else {
        return relatedSuggestionResults.getSuggestions();
    }
}

返回的字符串数组就是我们要的searchKey的相关词汇．

这些服务也可以通过 url 直接得到．比如

http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=ipod

返回的结果是
