App based on Semantic Parsing

Where do I go next?

• If you're new to semantic parsing, you can learn more from the background reading section of the tutorial.
• Install SEMPRE using the instructions under Installation below.
• Walk through the tutorial to get a hands-on introduction to semantic parsing through SEMPRE.
• Read the complete documentation to learn about the different components in SEMPRE.

Installation

Requirements

You must have the following already installed on your system.

• Java 8 (not 7)
• Ant 1.8.2
• Ruby 1.8.7 or 1.9
• wget

Other dependencies will be downloaded as you need them. SEMPRE has been tested on Ubuntu Linux 12.04 and MacOS X. Your mileage will vary depending on how similar your system is.

Easy setup

1. Clone the GitHub repository:

    git clone https://github.com/percyliang/sempre
   

2. Download the minimal core dependencies (all dependencies will be placed in lib):

    ./pull-dependencies core
   

3. Compile the source code (this produces libsempre/sempre-core.jar):

    ant core
   

4. Run an interactive shell:

    ./run @mode=simple
   

   You should be able to type the following into the shell and get the answer (number 7):

    (execute (call + (number 3) (number 4)))
   

To go further, check out the tutorial and then the full documentation.

Virtuoso graph database

If you will be using natural language to query databases (e.g., Freebase), then you will also need to setup your own Virtuoso database (unless someone already has done this for you):

# For Ubuntu, make sure these dependencies are installed
sudo apt-get install -y automake gawk gperf libtool bison flex libssl-dev

# Clone the repository
git clone https://github.com/openlink/virtuoso-opensource
cd virtuoso-opensource
git checkout tags/v7.0.0

# Configure
./autogen.sh
mv INSTALL INSTALL.txt  # Avoid conflict on case-insensitive file systems
./configure --prefix=$PWD/install

# Make (this takes a while)
make
make install
cd ..
