+Development Using Docker
+------------------------
+
+Develpers can work on PaddlePaddle using Docker.  This allows
+developers to work on different platforms -- Linux, Mac OS X, and
+Windows -- in a consistent way.
+
+The general development workflow with Docker and Bazel is as follows:
+
+1. Get the source code of Paddle:
+
+   .. code-block:: bash
+
+      git clone --recursive https://github.com/paddlepaddle/paddle
+
+
+2. Build a development Docker image `paddle:dev` from the source code.
+   This image contains all the development tools and dependencies of
+   PaddlePaddle.
+
+
+   .. code-block:: bash
+
+      cd paddle
+      docker build -t paddle:dev -f paddle/scripts/docker/Dockerfile .
+
+
+3. Run the image as a container and mounting local source code
+   directory into the container.  This allows us to change the code on
+   the host and build it within the container.
+
+   .. code-block:: bash
+
+      docker run \
+       -d # run the container in background mode \
+       --name paddle # we can run a nginx container to serve documents \
+       -p 2022:22    # so we can SSH into this container \
+       -v $PWD:/paddle # mount the source code \
+       -v $HOME/.cache/bazel:/root/.cache/bazel # mount Bazel cache \
+       paddle:dev
+
+4. SSH into the container:
+
+   .. code-block:: bash
+
+      ssh root@localhost -p 2022
+
+5. We can edit the source code in the container or on this host.  Then
+   we can build using cmake
+
+   .. code-block:: bash
+
+      cd /paddle # where paddle source code has been mounted into the container
+      mkdir -p build
+      cd build
+      cmake -DWITH_TESTING=ON ..
+      make -j `nproc`
+      CTEST_OUTPUT_ON_FAILURE=1 ctest
+
+   or Bazel in the container:
+
+   .. code-block:: bash
+
+      cd /paddle
+      bazel test ...

 ## Network Architecture
 You will describe four kinds of network architectures in this section.

+# 语义角色标注教程 #
+
+语义角色标注（Semantic role labeling, SRL）是浅层语义解析的一种形式，其目的是在给定的输入句子中发现每个谓词的谓词论元结构。 SRL作为很多自然语言处理任务中的中间步骤是很有用的，如信息提取、文档自动分类和问答。 实例如下 [1]:
+
+ [ <sub>A0</sub> He ] [ <sub>AM-MOD</sub> would ][ <sub>AM-NEG</sub> n’t ] [ <sub>V</sub> accept] [ <sub>A1</sub> anything of value ] from [<sub>A2</sub> those he was writing about ]. 
+
+- V: 动词
+- A0: 接受者
+- A1: 接受的东西
+- A2: 从……接受
+- A3: 属性
+- AM-MOD: 情态动词 
+- AM-NEG: 否定
+
+给定动词“accept”，句子中的组块将会扮演某些语义角色。这里，标签方案来自 Penn Proposition Bank。
+
+到目前为止，大多数成功的SRL系统是建立在某种形式的句法分析结果之上的，使用了基于句法结构的预定义特征模板。 本教程将介绍使用深度双向长短期记忆（DB-LSTM）模型[2]的端到端系统来解决SRL任务，这在很大程度上优于先前的最先进的系统。 这个系统将SRL任务视为序列标注问题。
+
+## 数据描述
+相关论文[2]采用 CoNLL-2005＆2012 共享任务中设置的数据进行训练和测试。由于数据许可的原因，演示采用 CoNLL-2005 的测试数据集，可以在网站上找到。
+
+用户只需执行以下命令就可以下载并处理原始数据：
+
+```bash
+cd data
+./get_data.sh
+```
+`data `目录会出现如下几个新的文件：
+```bash
+conll05st-release：the test data set of CoNll-2005 shared task 
+test.wsj.words：the Wall Street Journal data sentences
+test.wsj.props:  the propositional arguments
+feature: the extracted features from data set
+```
+
+## 训练
+### DB-LSTM
+请参阅情感分析的演示以了解有关长期短期记忆单元的更多信息。
+
+与在 Sentiment Analysis 演示中使用的 Bidirectional-LSTM 不同，DB-LSTM 采用另一种方法来堆叠LSTM层。首先，标准LSTM以正向处理该序列。该 LSTM 层的输入和输出作为下一个 LSTM 层的输入，并被反向处理。这两个标准 LSTM 层组成一对 LSTM。然后我们堆叠一对对的 LSTM 层后得到深度 LSTM 模型。
+
+下图展示了时间扩展的2层 DB-LSTM 网络。
+<center>
+![pic](./network_arch.png)
+</center>
+
+### 特征
+两个输入特征在这个流程中起着至关重要的作用：predicate（pred）和argument（arguments）。 还采用了两个其他特征：谓词上下文（ctx-p）和区域标记（mr）。 因为单个谓词不能精确地描述谓词信息，特别是当相同的词在句子中出现多于一次时。 使用谓词上下文，可以在很大程度上消除歧义。类似地，如果它位于谓词上下文区域中，则使用区域标记 m<sub>r</sub> = 1 来表示参数位置，反之则 m<sub>r</sub> = 0。这四个简单的特征是我们的SRL系统所需要的。上下文大小设置为1的一个样本的特征如下[2]所示：
+<center>
+![pic](./feature.jpg)
+</center>
+
+在这个示例中，相应的标记句子是：
+
+[ <sub>A1</sub> A record date ] has [ <sub>AM-NEG</sub> n't ] been [ <sub>V</sub> set ] . 
+
+在演示中, 我们采用上面的特征模板, 包括：  `argument`, `predicate`, `ctx-p (p=-1,0,1)`, `mark` 并使用 `B/I/O` 方案来标记每个参数。这些特征和标签存储在 `feature` 文件中, 用`\t`分割。
+
+### 数据提供
+
+`dataprovider.py` 是一个包装数据的 Python 文件。 函数 `hook()` 定义了网络的数据槽。六个特征和标签都是索引槽。
+```
+def hook(settings, word_dict, label_dict, **kwargs):
+    settings.word_dict = word_dict
+    settings.label_dict = label_dict
+    #all inputs are integral and sequential type
+    settings.slots = [
+        integer_value_sequence(len(word_dict)),
+        integer_value_sequence(len(predicate_dict)),
+        integer_value_sequence(len(word_dict)),

+        integer_value_sequence(2),
+        integer_value_sequence(len(label_dict))]
+```
+相应的数据迭代器如下：

+                  ctx_0_slot, ctx_p1_slot, ctx_p2_slot, mark_slot, label_slot
+```
+函数 `process` 返回8个特征list和1个标签list。

+### 预测
+预测脚本是 `predict.sh`，用户只需执行：

+  ./predict.sh
+  
+```
+在`predict.sh`中，用户应该提供网络配置文件，模型路径，标签文件，字典文件，特征文件。

+
+`predict.py` 是主要的可执行python脚本，其中包括函数：加载模型，加载数据，数据预测。网络模型将输出标签的概率分布。 在演示中，我们使用最大概率的标签作为结果。用户还可以根据概率分布矩阵实现柱搜索或维特比解码。

+预测后，结果保存在 `predict.res` 中。

+
+### 测试
+测试脚本是 `test.sh`, 执行:
+```bash
+  ./test.sh
+```
+`tesh.sh` 的主要部分：
+```
+paddle train \
+  --config=./db_lstm.py \
+  --model_list=$model_list \
+  --job=test \
+  --config_args=is_test=1 \
+```
+
+  - \--config=./db_lstm.py: 网络配置文件
+  - \--model_list=$model_list.list: 模型列表文件
+  - \--job=test: 指示测试任务
+  - \--config_args=is_test=1: 指示测试任务的标记
+  - \--test_all_data_in_one_period=1: 在一个周期内测试所有数据
+  
+
+### 预测
+预测脚本是 `predict.sh`，用户只需执行：
+```bash
+  ./predict.sh
+  
+```
+在`predict.sh`中，用户应该提供网络配置文件，模型路径，标签文件，字典文件，特征文件。
+```
+python predict.py 
+     -c $config_file \
+     -w $best_model_path \
+     -l $label_file \
+     -p $predicate_dict_file  \
+     -d $dict_file \
+     -i $input_file \
+     -o $output_file
+```
+
+`predict.py` 是主要的可执行python脚本，其中包括函数：加载模型，加载数据，数据预测。网络模型将输出标签的概率分布。 在演示中，我们使用最大概率的标签作为结果。用户还可以根据概率分布矩阵实现集束搜索或维特比解码。
+
+预测后，结果保存在 `predict.res` 中。
