Avicenna Drug Info Line: A Speech Recognizer System

Zina Saadi Page 1

Avicenna Drug Info Line

Inspired by Avicenna’s major contribution to medical science and his

famous book al-Qanun fi al-Tibb1 (the Canons of Medicine), which is

an immense encyclopedia of medicine extending over a million words.

It reviewed the medical knowledge available from ancient and Muslim

sources. The Qanun 2 book deals with general medicine, over 760

drugs, diseases affecting all parts of the body from head to foot,

especially pathology and pharmacology.

1 Al-Qanun fi Al-Tibb is the title of the book in Arabic which translates literally to “The Law in Medicine”

2 Pronounced Qanoon

1.2 What is Avicenna Drug Info Line?

Avicenna Drug Info Line (Avicenna DIL) is a speech system recognizer that allows callers to get the best detailed information about drugs from http://www.rxwiki.com --which is a drugs Wikipedia updated by pharmacists-- via coherent and friendly interactions. Avicenna DIL incorporates Aaron Copland’s “Appachian Spring” classical music excerpt3, which adds a relaxing theme to its overall picture.

The system is accessible from anywhere and anytime by calling 1-877-338-6225, using the user id 9193219 and the pin: 1980.

Callers would call to lookup drugs information, including: What is it used for?

How to take the drug? How will it benefit you?

How does the drug function? How is a certain drug available?

What are its possible side effects? What should you do in case of overdose?

What are its possible interactions with other drugs? What are the warnings and cautions should you know about?

2 Major Design Specifications

2.1 Design Overview

Avicenna Drug Info line’s design is a good design because it fits most of the 10 principles of good design for Dieter Rams

4. It:

1. Combines two of important fields namely the automatic speech recognition field and the text processing/data mining field, which makes the system Innovative.

2. Makes the product useful since it satisfies the needs of people, especially since the system is able to offer callers the most updated information and detail of the top 100 drugs via the telephone. This also makes the design more concerned with the environment since it copes with the current lifestyle of people which is characterized by a busy lifestyle, and the wide usage of wireless communication technologies including cell phones and text messaging over the phone. Avicenna Drug info Line connects people with information retrieved from the internet wherever they are, and anytime they wish to learn about a certain drug.

3. Incorporate a female voice throughout the entire dialogue prompts (except for the information retrieved dynamically), as well as a smooth flow of control for the caller and the system which adds beauty to the system and makes the design aesthetic.

4. Is as little design as possible since it incorporates a small set of states despite the larger functionality it provides.

5. Is durable since the system can be functional even if the wiki pages are updated.

2.2 Functionalities Overview

Avicenna DIL5 has dual levels of functionalities namely: the surface functionality and the deep-structure functionality. Both levels of functionalities interact with each other to form the unique design for the speech system which was defined in section 2.1.

2.2.1 Surface Functionality

The surface functionality that Avicenna DIL uses is the speech dialogue interface that is apparent to the caller. It incorporates over 45 self-recorded prompts to give the caller the feeling that he is talking to a human. Avicenna DIL uses 11 background music files to polish the transitions of moving from one state to another for a smooth caller-system interaction.

2.2.2 Deep-Structure Functionality

The deep-structure functionality is what actually happens behind the scenes. It is defined as the deep-structure functionality of the system, because first it is deep in the sense that it is not apparent to the caller and second it has a complex structure that is deep to the level that the caller would not even notice such complexity. In addition, it incorporates cutting edge technologies of using the scripting language Ruby, the markup-language VoiceXML which is a format as XML that can be interpreted as speech, CGI files and Bevocal Café as the VXML interpreter.

2.3 Project Plan The completion of Avicenna DIL wouldn’t have been possible without a project plan (often referred to as the schedule of a project). The project plan measures a day by 8 working hours. In addition, since there was only one main developer engineer, who took the major responsibility of the project preparation, design, implementation, QA and debugging, the dependency, column was removed from the project plan, as well as the percent complete column since at this stage all tasks have been successfully accomplished. The image below, illustrates the project plan created for Avicenna DIL:

5 The paper will refer for Avicenna Drug Info Line as “Avicenna DIL” for simplicity


Zina Saadi Page 6

2.4 Design Flow-Chart The original flow-chart for this project consisted of over 15 states. However after the completion of the code implementation, the number of the states was reduced due to the feature of static-prompts reusability which allows the system to have a polymorphic state. A polymorphic state is a state that can have different specification/behavior according to certain given input which in this case is called a parameter. For instance, the drug info type state (1080), can act as a drug “benefits”, “side effects” or any other type of information specified by the caller by using a set of static prompts in addition to dynamic prompts which identify its current type of behavior (i.e. drug info type). Below is the complete flow chart of the system. Note that the parameters passed to polymorphic states are specified in the arrows combining them with other states.

3 Implementation

3.1 Data Collection According to the initial design implementation, data was supposed to be downloaded via a UNIX crawler command (wget) which would collect drugs information from well known websites (see table below). However, since all of the encountered drugs/medication websites disallowed automatic crawlers as sited in their robots.txt file in their root directories, static data collection was not possible.

Zina Saadi Page 19

An alternative solution was to collect the drugs information dynamically by automatically retrieving the drugs information from the web parsing the text and generating the data via vxml. After approximately 2 hours of web search through Google for a simple website about drugs, the website corresponding to the link < http://rxwiki.com/index.php?title=Main_Page> was found to be very useful for the following main reasons:

The website consists of a simple markup language (HTML)

There were no Javascripts or other forms of scripts used when retrieving various drug information.

There were no fancy uses of frames, flash or other GUI forms that are hard to scrape via Ruby.

3.2 Drugs Page Structure There are two major formats that this project needed to account for:

1. The top hundred drugs list 2. The individual drugs info pages

The page structure for the top 100 drugs consists of a list of all drugs in one block of the html page which was not hard to extract using methods in the ruby gem ‘hpricot’ as the list looks like the following image:

However, the pages for the drug information are not uniform for all drugs; 92% of the drugs fall into group 1 whereas the rest 8% are distributed over 5 more groups (see Appendix B for the list of drugs in each category).

http://rxwiki.com/index.php?title=Main_Page

Group1 img1 Group2 img2




Zina Saadi Page 21

3.3 Text Normalization Text normalization was an important element in the implementation of Avicenna DIL since the speech system is unable to read many ASCII characters such as carriage return or tabs {“\t”,”\n”,”\r”}. In addition to symbols and special characters removal, vision words removal was crucial. For instance text containing spacial adverbs such as “below” or “above” would not be appropriate for a TTS to say it, and thus it requires the system to remove it.

4 Possible Future Improvements Avicenna Drug Info Line can be improved in various ways including:

1. Internationalization Expansion: Prompts can be translated in the various languages that preserve the same drugs naming convention. Possible languages could include: French, Spanish, Modern Standard Arabic (Assuming French influenced Arabic countries).

2. Expanding the drugs list is important, especially since one of the initial testers of the system reported that she was not able to find simple drugs names as Aspirin (see Appendix D: Roza Safarova’s email).
