Wiki Tests For Android

Hello and welcome to Langtech’s blog. This blog contain material and links to sites useful for learning and teaching English (“WikiTests”, “On the Web”) within the context of Web Semantics. You can also find a description of some of the Software developed by Langtech. If your looking for information about the Wiki Tests for Android app then you should go here: (play store, help file, online demo ).

On The Web

This blog contains reading material and information about the English language. You can also find pointers to online resources for learning and teaching English and developing educational software.


The WikiTests page and blog contains vocabulary tests constructed automatically from Wikipedia articles by Langtech’s English Language Assistant (ELA). There are two types of test in each post. The first test contains words with their letters scrambled up (or sometimes not). The student’s task is to unscramble them. The second test is an open cloze test where the words from the first test, with their letters scrambled, have been removed and replaced with underscores. The original text appears at the end of the test along with a list of the most important words found and collocations. The tests are classified as either Intermediate or above. If you would like to be informed about the latest tests then subscribe to our RSS feed.

The ELA was developed on top of Flask which is a Web Development Framework for Python. In the words of the authors, “Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions”.


You might also like to read about Langtech’s Web Server which is an extended version of the Common Lisp Hypermedia Server (CL-HTTP). For those of you who like programming, you can also read about the LISP Technologies that are available for developing applications. If you don’t like programming then don’t worry, because there are lots of tools available for both the novice and professional.

Langtech’s Web Server is now being ported to Python as a part of the ELA project. Sadly, LISP is no longer an appropriate development platform for Natural Language Technologies, hence the move to a Python based Web Development Framework. Python comes with an excellent choice of libraries for Natural Language Processing and the development of Semantic Web applications. The WikiTests blog is powered by Langtech’s new webserver. On this site you can generate a random crossword, multiple choice vocabulary tests and open cloze tests based on wikipedia articles. The list of resources available on this site changes at a slow pace but a steady one
