Umsatzsteuer Rechnungsausstellung 

TPA Steuerberatung has developed an innovative tool together with LexisNexis that offers orientation in the highly complex area of ​​sales tax. 

The Lexis tool sales tax is a digital assistant for sales tax questions or individual invoice issues on the incoming and outgoing side. It makes their daily work easier for tax consultants and lawyers: As with a decision tree, the assistant selects the right branch depending on the answers and adapts its follow-up questions accordingly. With the tool, the legal assessment succeeds right from the start and later problems in tax audits or accusations of financial criminal law can be avoided.

ErbRechner (Lexis Nexis Austria)

ErbRechner is an inheritance calculation tool for lawyers. Key questions, such as unworthiness, can only be answered by a professional. The lawyer can record all assets, liabilities, estate, donations and all the heirs, and the application will calculate the inherited and compulsory portions for all heirs both as quotas and the actual amount. You can read all about ErbRechner here!.

LPA/VisiRule is part of the EMDS.. 


The Ecosystem Management Decision Support (EMDS) system is a state-of-the-art modeling framework that supports environmental decision analysis and planning. EMDS integrates the latest technology from geographic information systems (GIS) as well as logic-based reasoning and a variety of modeling technologies. This provides explicit, practical decision support for strategic and tactical planning as well as adaptive management. Because EMDS is a generic solution framework, it can be applied to an extremely broad array of problems at virtually all spatial scales.

EMDS Overview


AllerGenius is an expert system for the interpretation of allergen arrays from Phenomix. Precision medicine (PM) is changing the scope of allergy diagnosis and treatment. The advent of low-cost widely available allergen array tests has lead to the need for the expert interpretation of the various markers.

The complexity of molecular allergy historically confined the interpretation of these tests to a small number of highly skilled allergists. AllerGenius allows allergists to access the most current and specialist interpretation of allergen arrays for their patients. Less skilled allergists can benefit from modern technology associated with a complete and dedicated interpretation system. 
Expert reports are generated in multiple European languages including Italian, Russian, Croatian and German.

      In my many years of software development, this is the first time that things were better than expected! Working with the LPA team of engineers and its software has been a pleasure. They have managed not to just to meet my current needs but anticipate most of my future requirements. As such, the core software infra-structure for AllerGenius has remained intact and largely untouched for several years and through several incarnations of the product.

PALTESTER is a desktop software application from ESROE developed using LPA Prolog that enables the analysis of the identification performance of an automatic Radar ESM system. It was created to provide military analysts with tools to analyse the identification performance of ESROE’s THORONDIR emitter identification software used in operational Radar ESM systems.

HOOF National Hunt Race Ratings are designed as a statistics-grounded value approach to horse racing over jumps in the UK. Unlike conventional race ratings, they offer the backer an authoritative guide to both form and value. The program which generates the ratings uses an implementation of Bayes’ theorem written in LPA Prolog to calculate each horse’s chance of winning. The resulting figures are then recalculated to give an edge in the backer’s favour. Hence the acronym: Horserace Optimum Odds Forecast.


CASSANDRA is a platform developed by KnowGravity in Zurich, Switzerland. It is assistant-based and guides the users through their tasks in business, systems and software engineering. It analyses project data from many familiar UML®-based CASE tools, generates the appropriate questions or proposes the next steps in order to move the process forward.

By turning UML models into precise xUML models (Executable UML), it becomes possible to define an environment in which such implementation-independent analysis models can be executed without considering technical details of the target platform.

InFlow is a leading Social Network Analysis tool from OrgNet which performs network analysis AND network visualization in one integrated product -- no passing files back and forth between different programs like other tools.


What is mapped in one window is measured in the other window -- what you see, is what you measure. InFlow excels at what-if analysis -- change the network, get new metrics -- just 2 clicks of the mouse. You do not need to be an expert in statistics to use InFlow.

InFlow & Transmission Network Analysis (TNA)


You can read how InFlow has been used to model network transmission for contagious diseases. Transmission Network Analysis (TNA) is best applied early in an outbreak before a mass outbreak sets in to a local area. Tracking the early cases provides great insight into how, when, and where the contagion is spreading. Data collection is difficult but always proves worthy to the understanding and management of the outbreak.
