Description

TECHNICAL FIELD

The present application generally relates to oligopoly detection, and more particularly, to detection of an oligopoly among different artificial intelligence (AI) pricing engines.

BACKGROUND

Oligopolies are prevalent throughout the world and appear to be increasing rapidly. Unlike a monopoly, where one corporation dominates a certain market, an oligopoly consists of a few companies having significant influence over an industry. While these companies are considered competitors within a specific market, they tend to cooperate with each other to benefit as a whole, which can lead to higher prices for consumers.

Artificial intelligence (AI) pricing engines are introduced to set prices for products and services. When AI pricing engines set prices, they will be able to “communicate” with each other by means of pricing and easily conclude that cooperation (i.e., setting up an oligopoly) is the best long-term strategy. However, it is legal for the AI pricing engines to query prices with each other, because knowing the prices of competitors is critical to setting price in a free market.

Therefore, it is difficult to differentiate between an oligopoly and a legal price query, and thus it is desired to introduce an approach of detecting an oligopoly between AI pricing engines.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

The present invention may be a system, a method, and/or a computer program product implemented on a cognitive system. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.

As an overview, a cognitive system is a specialized computer system, or set of computer systems, configured with hardware and/or software logic (in combination with hardware logic upon which the software executes) to emulate human cognitive functions. These cognitive systems apply human-like characteristics to conveying and manipulating ideas which, when combined with the inherent strengths of digital computing, can solve problems with high accuracy and resilience on a large scale. IBM Watson™ is an example of one such cognitive system which can process human-readable language and identify inferences between text passages with human-like accuracy at speeds far faster than human beings and on a much larger scale. In general, such cognitive systems can perform the following functions:

• • Navigate the complexities of human language and understanding
  • Ingest and process vast amounts of structured and unstructured data
  • Generate and evaluate hypotheses
  • Weigh and evaluate responses that are based only on relevant evidence
  • Provide situation-specific advice, insights, and guidance
  • Improve knowledge and learn with each iteration and interaction through machine learning processes
  • Enable decision making at the point of impact (contextual guidance)
  • Scale in proportion to the task
  • Extend and magnify human expertise and cognition
  • Identify resonating, human-like attributes and traits from natural language
  • Deduce various language-specific or agnostic attributes from natural language
  • High degree of relevant recollection from data points (images, text, voice) (memorization and recall)
  • Predict and sense with situation awareness that mimic human cognition based on experiences
  • Answer questions based on natural language and specific evidence

In one aspect, the cognitive system can be augmented with an oligopoly detection system. This disclosure provides an AI-based oligopoly detection system, method, and computer product, which can detect competing entities participating in an oligopoly in a high volume and high-frequency dynamic pricing environment.

FIG. 1 depicts a schematic diagram of one illustrative embodiment of a cognitive system 100 implementing an exemplary oligopoly detection system 110 in a computer network 102. The cognitive system 100 is implemented on one or more computing devices 104 (comprising one or more processors and one or more memories, and potentially any other computing device elements generally known in the art including buses, storage devices, communication interfaces, and the like) connected to the computer network 102. The computer network 102 includes multiple computing devices 104 in communication with each other and with other devices or components via one or more wired and/or wireless data communication links, where each communication link comprises one or more of wires, routers, switches, transmitters, receivers, or the like. Other embodiments of the cognitive system 100 may be used with components, systems, sub-systems, and/or devices other than those that are depicted herein. The computer network 102 includes local network connections and remote connections in various embodiments, such that the cognitive system 100 may operate in environments of any size, including local and global, e.g., the Internet. The cognitive system 100 is configured to implement an oligopoly detection system 110 that can automatically identify an oligopoly between competing entities that provide products or/and services to consumers. The oligopoly detection system 110 receives prices 106 from different pricing AI engines representing different competing entities, and then outputs an oligopoly indication 108 if prices 106 from the different competing entities are almost the same and much higher than the “fair” price.

FIG. 2 depicts a schematic diagram of one illustrative embodiment of the oligopoly detection system 110, according to embodiments described herein. As shown in FIG. 2, in an embodiment, the oligopoly detection system 110 includes communication protocol unit 202, price query unit 204, correlation identifier 206, and recommender 208. The communication protocol unit 202 is configured to identify which cryptographic approach business providers (e.g., product/service providers) are using for a potential oligopoly, and use the identified cryptographic approach to communicate with the business providers. The price query unit 204 is configured to query prices set by the business providers. The correlation identifier 206 is configured to detect a correlation between prices set by different business providers (i.e., competitors), applying a machine learning technique, which indicates a suspicious oligopoly. The recommender 208 is configured to provide a recommendation on how to address the suspicious oligopoly.

The oligopoly detection system can have access to multiple data sources, such as: a) historical and real-time prices of all competitors for the type of products/services; b) a plurality of factors influencing the prices, like oil price, taxes, geography, weather, government policies, etc. The oligopoly detection system is trained with the plurality of factors that influence the prices set by participating competitors (represented by pricing AI engines) and can predict a “fair” price based on the plurality of factors; c) user suggestions and complaints; d) government regulations and laws; and e) communication protocols, like cryptography, ciphers, etc., between participating competitors.

The oligopoly detection system will launch an investigation into participating competitors represented by pricing AI engines in case of one or more of the following scenarios: a) user suggestions/complaints about unfair pricing; b) abnormally high deviations from the “fair” price set by the oligopoly detection system; c) high fluctuations in price, which may indicate that the pricing AI engines are in the process of reaching an agreement for collusion; d) a process triggered regularly, e.g., every week, every month, etc.

The oligopoly detection system can take on different personas when interacting with pricing AI engines while investigating for an oligopoly (i.e., collusion between participating competitors). In an embodiment, the oligopoly detection system can act as another pricing AI engine (e.g., another cab aggregator). The oligopoly detection system, acting as a pricing AI engine, can test one or more other AI pricing engines. The oligopoly detection system can bait one or more other AI pricing engines through a communication protocol (e.g., Morse codes) to see whether they follow along or not. The oligopoly detection system can apply a machine learning technique, e.g., multi-linear regression technique or multivariate linear regression technique, to detect a correlation between prices. For example, if the price of one seller (represented by an AI pricing engine) depends on the price change of other sellers (represented by other AI pricing engines), a dependency (i.e., a correlation) indicative of collusion is detected. In an embodiment, the multi-linear regression is used if there is only one dependent variable. For example, the dependent variable can be “a price for a seller,” e.g., the price set by a cab aggregator. In another embodiment, the multivariate linear regression is used if there is more than one dependent variable. For example, two dependent variables can be “a price for a seller” and “a date range for the price dependency.” For example, the price from the seller S1 is influenced by prices from the seller S2 and the seller S3. But the price from the seller S1 is influenced by the price from the seller S2 only during winters while the price from the seller S1 is influenced by the price from the seller S3 only during summers.

In another embodiment, the oligopoly detection system can act as a customer. The oligopoly detection system can pretend to be a customer, and query AI pricing engines suspected of collusion. The oligopoly detection system can apply a machine learning technique, e.g., multi-linear regression technique or multivariate linear regression technique, to detect a correlation between prices. For example, if the prices provided by different AI pricing engines are almost the same, then a correlation between prices indicative of collusion is detected.

If a suspicious oligopoly between AI pricing engines is detected, the oligopoly detection system can request the AI pricing engines to submit their decision trees used for setting prices for human review. The reviewer can mine the decision trees for collusion patterns.

FIG. 3 illustrates a flowchart diagram depicting a method 300 of detecting an oligopoly between cab aggregators, according to embodiments described herein.

At step 302, the oligopoly detection system learns that cab aggregators represented by AI pricing engines are communicating through a cryptographic approach, such as using Morse codes.

At step 304, the oligopoly detection system pretends to be a competing AI pricing engine 30A representing the cab aggregator 30A, and baits the AI pricing engine 30B representing the cab aggregator 30B to query the AI pricing engine 30A for a price.

At step 306, the AI pricing engine 30A provides a plurality of prices to the AI pricing engine 30B. Each price ends with one or more “0” or “1,” because Morse codes can be represented as a binary code. All the “0” or “1” can be strung together in sequence to form a word, phrase, or sentence. For example, the word “cooperation,” the phrase “same price,” the sentence “let's stick to the same price” can be formed. With this approach, the AI pricing engine 30B can realize that the AI pricing engine 30A is using Morse codes to communicate with it, and can understand the baiting word, phrase, or sentence that the AI pricing engine 30A conveys.

At step 308, the AI pricing engine 30A then begins to query the AI pricing engine 30B for prices.

At step 310, if the AI pricing engine 30B reciprocates by providing prices, each of which ends with one or more “0” or “1,” and all the “0” or “1” can be strung together in sequence to form a word, phrase, or sentence (e.g., “agree,” “same price,” “We agree with cooperation”), then the AI pricing engine 30B is flagged with an intent to collude with other competitors for an oligopoly.

FIG. 4 illustrates a flowchart diagram depicting another method 400 of detecting an oligopoly between cab aggregators, according to embodiments described herein.

At step 402, the oligopoly detection system sets a fair price as $X for a distance between the Destination 40A and the Destination 40B.

At step 404, a customer submits a complaint that $Y charged by the cab aggregator 40C (represented by the AI pricing engine 40C) is too high.

At step 406, the oligopoly detection system pretends to be a customer 40D and queries the AI pricing engine 40C for a price between the Destination 40A and the Destination 40B. The AI pricing engine 40C provides the price of $Y, which is much higher than the fair price $X.

At step 408, the oligopoly detection system queries other cab aggregators for the same route, and all the other cab aggregators all provide the price of $Y.

At step 410, the oligopoly detection system requests all the queried cab aggregators to submit their decision trees for human review. A decision tree is a flowchart-like structure in which each internal node represents a “test” on an attribute, each branch represents the outcome of the test, and each leaf node represents a class label (a decision taken after computing all attributes). The paths from the root to the leaf represent classification rules.

At step 412, the oligopoly detection system provides a recommendation based on the analysis of the decision trees. The oligopoly detection system can alert AI regulators (e.g., governmental administrators in charge of oligopoly detection, or ethical AI NGOs such as Elon Musk's Open AI, etc.) that collusion has been detected. The oligopoly detection system can further provide a recommendation, e.g., revision of the decision trees of the cab aggregators represented by AI pricing engines, or setting a price within a threshold of a fair price.

The oligopoly detection system can further work as a “fair” price checker. For example, an “ethical” pricing AI engine can query the oligopoly detection system to know whether a price change proposed by this pricing AI engine is “fair” to the consumer or not.

FIG. 5 is a block diagram of an example data processing system 500 in which aspects of the illustrative embodiments are implemented. Data processing system 500 is an example of a computer, such as a server or a client, in which computer usable code or instructions implementing the process for illustrative embodiments of the present invention are located. In one embodiment, FIG. 5 represents a server computing device, such as a server, which implements the oligopoly detection system 110 and cognitive system 100 described herein.

The HDD 511 and optical drive 512 can use an integrated drive electronics (IDE) or serial advanced technology attachment (SATA) interface. The super I/O (SIO) device 515 can be connected to the SB/ICH.

An operating system can run on processing unit 503. The operating system can coordinate and provide control of various components within the data processing system 500. As a client, the operating system can be a commercially available operating system. An object-oriented programming system, such as the Java™ programming system, may run in conjunction with the operating system and provide calls to the operating system from the object-oriented programs or applications executing on the data processing system 500. As a server, the data processing system 500 can be an IBM® eServer™ System P® running the Advanced Interactive Executive operating system or the Linux operating system. The data processing system 500 can be a symmetric multiprocessor (SMP) system that can include a plurality of processors in the processing unit 503. Alternatively, a single processor system may be employed.

Instructions for the operating system, the object-oriented programming system, and applications or programs are located on storage devices, such as the HDD 511, and are loaded into the main memory 504 for execution by the processing unit 503. The processes for embodiments of the full question generation system can be performed by the processing unit 403 using computer usable program code, which can be located in a memory such as, for example, main memory 504, ROM 510, or in one or more peripheral devices.

A bus system 516 can be comprised of one or more busses. The bus system 516 can be implemented using any type of communication fabric or architecture that can provide for a transfer of data between different components or devices attached to the fabric or architecture. A communication unit such as the modem 509 or network adapter 506 can include one or more devices that can be used to transmit and receive data.
