Apache Tika 1.11 发布，此版本包括大量的改进和 bug 修复： * Java7 API support for allowing java.nio.file.Path as method arguments was added to Tika and to ParsingReader, TikaFileTypeDetector, and to Tika Config (TIKA-1745, TIKA-1746, TIKA-1751). * MIME support was added for WebVTT: The Web Video Text Tracks Format files (TIKA-1772). * MIME magic improved to ensure emails detected as message/rfc822 (TIKA-1771). * Upgrade to Jackcess Encrypt 2.1.1 to avoid binary incompatibility with Bouncy Castle (TIKA-1736). * Make div and other markup more consistent between PPT and PPTX (TIKA-1755). * Parse multiple authors from MSOffice's semi-colon delimited author field (TIKA-1765). * Include CTAKESConfig.properties within tika-parsers resources by default (TIKA-1741). * Prevent infinite recursion when processing inline images in PDF files by limiting extraction of duplicate images within the same page (TIKA-1742). * Upgrade to POI 3.13-final (via Andreas Beeker) (TIKA-1707). * Upgraded tika-batch to use Path throughout (TIKA-1747 and (TIKA-1754). * Upgraded to Path in TikaInputStream (via Yaniv Kunda) (TIKA-1744). * Changed default content handler type for "/rmeta" in tika-server to "xml" to align with "-J" option in tika-app. Clients can now specify handler types via PathParam. (TIKA-1716). * The fantastic GROBID (or Grobid) GeneRation Of BIbliographic Data for machine learning from PDF files is now integrated as a Tika parser (TIKA-1699, TIKA-1712). * The ability to specify the Tesseract Config Path was added to the OCR Parser (TIKA-1703). * Upgraded to ASM 5.0.4 (TIKA-1705). * Corrected Tika Config XML detector definition explicit loading of MimeTypes (TIKA-1708) * In Tika Parsers, Batch, Server, App and Examples, use Apache Commons IO instead of inlined ex-Commons classes, and the Java 7 Standard Charset definitions (TIKA-1710) * Upgraded to Commons Compress 1.10, which enables zlib compressed archives support (TIKA-1718) 详细改进请看： http://www.apache.org/dist/tika/CHANGES-1.11.txt 下载：http://www.apache.org/dyn/closer.cgi/tika/apache-tika-1.11-src.zip Apache Tika 同时提供在 Maven： http://repo1.maven.org/maven2/org/apache/tika/ 更多内容请看发行说明。 Tika是一个内容抽取的工具集合(a toolkit for text extracting)。它集成了POI, Pdfbox 并且为文本抽取工作提供了一个统一的界面。其次，Tika也提供了便利的扩展API，用来丰富其对第三方文件格式的支持。 在当前的0.2-SNAPSHOT版本中， Tika提供了对如下文件格式的支持: PDF - 通过Pdfbox MS-* - 通过POI HTML - 使用nekohtml将不规范的html整理成为xhtml OpenOffice 格式 - Tika提供 Archive - zip, tar, gzip, bzip等 RTF - Tika提供 Java class - Class解析由ASM完成 Image - 只支持图像的元数据抽取 XML Tika的API十分便捷，核心是Parser interface，其中定义了一个parse方法： public void parse(InputStream stream, ContentHandler handler, Metadata metadata) 用stream参数传递需要解析的文件流， 文本内容会被传入handler，而元数据会更新至metadata。 可以使用Tika的ParserUtils工具来根据文件的mime-type来得到一个适当的Parser来进行解析工作。或者Tika还提供了一个AutoDetectParser根据不同的二进制文件的特殊格式 (比如说Magic Code)，来寻找适合的Parser。 Apache Tika 1.11 发布，内容抽取工具集合下载地址
