FOLT Überblick Stand 03.07.2009; Dr. Klemens Waldhör

Overview


Goals
Three translation memory systems for one and the same process?
Software investments that make translation costs shoot through the roof?
Exchange formats that put the brakes on productivity?
FOLT (Forum Open Language Tools) is concerned with the entire process of producing multilingual
documentation. From the creation of the source text to production in foreign languages, we analyze our
processes for weaknesses and a lack of standardisation.

Primary objectives:
- Sharing experiences of processes using standard industry software
- Sharing experiences of the use of Open Source software
- Standardisation of interchange formats
-Testing new Open Source technologies and improving existing technologies in the translation market
- Public support for non-proprietary software and software development
- Publication of aims and results

Development of the OpenSource Translation
Memory system OpenTMS

4

OpenTMS Requirements
Software
Web based application
Server / Client Architecture
Thin client
No installation
No proprietary run time components
Preferred open source software
Modular software approach
OS independent operating system
Windows, Linux, Mac …
Standard hardware
Interfaces
Integration into CMS
Workflow management should be supported
Open source database
Basically all SQL da-tabases should be supported
Scalability
Single and multi user requirement

Implementation


Programming Language et al
Java
Java Coding Standards
Java Documentation Standard
Delivered as jar files
Eclipse
Data Sources
SQL DB: Hibernate based
Documentation UML
Generated ESS Model

14

Data Sources
Language related data are represented as “data sources”
Idea
Make the data access interface independent from the data itself
Not being restricted to SQL databases only
Also flat data or xml files
TMX, XLIFF files as a data source
…
Machine translation (MT) as data source
Spread sheets
E.g. Excel as terminology lists
Object Oriented Databases
DMS systems
“Web Sites” (http based interfaces)
Define a common interface for all access functions
Allows adaption to individual data source properties
e.g. read only data sources like MT

15

16

Core Data Model Status
Data Source methods defined
Are extended depending on needs and requirements
SQL
Access optimisation
Hibernate based
First version finished
Other OpenSource databases…
OODBS
DB4O partially implemented for testing purposes
Other data sources
TMX files
XLIFF files
MT
Google & Microsoft Translator

17

Data Source Core Functions
Data Sources
Create
Delete
Import TMX, XLIFF File
Export TMX, XLIFF File
Copy between data sources

18

Fuzzy Search – Core Function of TM
Step 1: Search in KD-TREE
Restricts the number of strings to search
Finds possible matching strings
Step 2: Levenshtein Similarity
Compare matches from step 1 now to determine
real similarity
Step 3: Get source and target MOLs / MUL
Create translation (alt-trans)

19

Data Source Configuration
SQL Data Source contained in hibernate
directory

Existing data sources contained in database

Translation Core Functions

Currently externally done Araya

Security

Managing Security


Security Levels
Level 0
No security procedures are applied, data are transferred as
they are.
Level 1
The communication channel is secured. It uses standard
secure protocols here.
Level 2
Encoding for security is done here on data level. Basically
this means that strings are encrypted when the are
communicated through a communication channel or are
written or retrieved from a database. This also involves
encrypted XLIFF files (resp. parts of it).
Level 4
GUI level related security

24

Security and Files
Protection of parts of
the document
Encrypt specific parts of
the xml documents
Additional security
when transferring files
Even if a file gets in the
wrong hands the file
cannot be read.
Secure XLIFF

Target
Secure TBX
Secure TMX
