1. UIMA 集成

　　你可以使用solr集成Apache的非结构化信息管理架构(UIMA).UIMA可以让你定义自己的分析引擎通道,逐步添加元数据到文档的标注.

　　关于Solr UIMA的更多信息,参考https://wiki.apache.org/solr/SolrUIMA.

1.1 Configuring UIMA

　solr UIMA的UpdateRequestProcessor是一个自定义的更新请求处理器.发送它们给UIMA管道,然后返回具有丰富元数据的文档.按照下面步骤配置UIMA:

　　1. solrconfig.xml,复制/solr-4.x.y/dist/solr-uima-4.x.y.jar包和它的contrib/uima/lib下面的类库到solr的类库目录下.

<lib dir="../../contrib/uima/lib" />

<lib dir="../../dist/" regex="solr-uima-\d.*\.jar" />

　　2.schema.xml中,添加元数据字段:

<field name="language" type="string" indexed="true" stored="true"  required="false" />

<field name="concept" type="string" indexed="true" stored="true" multiValued="true" required="false" />

<field name="sentence" type="text" indexed="true" stored="true" multiValued="true" required="false" />

　　3.在solrconfig.xml中添加如下片段:

<updateRequestProcessorChain name="uima">

    <processor

        class="org.apache.solr.uima.processor.UIMAUpdateRequestProcessorFactory">

        <lst name="uimaConfig">

            <lst name="runtimeParameters">

                <str name="keyword_apikey">VALID_ALCHEMYAPI_KEY</str>

                <str name="concept_apikey">VALID_ALCHEMYAPI_KEY</str>

                <str name="lang_apikey">VALID_ALCHEMYAPI_KEY</str>

                <str name="cat_apikey">VALID_ALCHEMYAPI_KEY</str>

                <str name="entities_apikey">VALID_ALCHEMYAPI_KEY</str>

                <str name="oc_licenseID">VALID_OPENCALAIS_KEY</str>

            </lst>

            <str name="analysisEngine">

                /org/apache/uima/desc/OverridingParamsExtServicesAE.xml

            </st

r>

                <!-- Set to true if you want to continue indexing even if text processing

                    fails. Default is false. That is, Solr throws RuntimeException and never

                    indexed documents entirely in your session. -->

                <bool name="ignoreErrors">true</bool>

                <!-- This is optional. It is used for logging when text processing fails.

                    If logField is not specified, uniqueKey will be used as logField. <str name="logField">id</str> -->

                <lst name="analyzeFields">

                    <bool name="merge">false</bool>

                    <arr name="fields">

                        <str>text</str>

                    </arr>

                </lst>

                <lst name="fieldMappings">

                    <lst name="type">

                        <str name="name">org.apache.uima.alchemy.ts.concept.ConceptFS</str>

                        <lst name="mapping">

                            <str name="feature">text</str>

                            <str name="field">concept</str>

                        </lst>

                    </lst>

                    <lst name="type">

                        <str name="name">org.apache.uima.alchemy.ts.language.LanguageFS</str>

                        <lst name="mapping">

                            <str name="feature">language</str>

                            <str name="field">language</str>

                        </lst>

                    </lst>

                    <lst name="type">

                        <str name="name">org.apache.uima.SentenceAnnotation</str>

                        <lst name="mapping">

                            <str name="feature">coveredText</str>

                            <str name="field">sentence</str>

                        </lst>

                    </lst>

                </lst>

        </lst>

    </processor>

    <processor class="solr.LogUpdateProcessorFactory" />

    <processor class="solr.RunUpdateProcessorFactory" />

</updateRequestProcessorChain>

　　4. 在solrconfig.xml中替换已经存在的UpdateRequestHandler或者创建新的UpdateRequestHandler.

<requestHandler name="/update" class="solr.XmlUpdateRequestHandler">

　　<lst name="defaults">

　　　　<str name="update.processor">uima</str>

　　</lst>

</requestHandler>
