We propose a novel probing method and benchmark called EUREQA. EUREQA is an entity-searching task where a model finds a missing entity based on described multi-hop relations with other entities. These deliberately designed multi-hop relations create deceptive semantic associations, and models must stick to the correct reasoning path instead of incorrect shortcuts to find the correct answer. Experiments show that existing LLMs cannot follow correct reasoning paths and resist the attempt of greedy shortcuts. Analyses provide further evidence that LLMs rely on semantic biases to solve the task instead of proper reasoning, questioning the validity and generalizability of current LLMs’ high performances.

LLMs make errors when correct surface-level semantic cues-entities are recursively replaced with descriptions, and the errors are likely related to token similarity. GPT-3.5-turbo is used for this example.

In EUREQA, every question is constructed through an implicit reasoning chain. The chain is constructed by parsing DBPedia. Each layer comprises three components: an entity, a fact about the entity, and a relation between the entity and its counterpart from the next layer. The layers stack up to create chains with different depths of reasoning. We verbalize reasoning chains into natural sentences and anonymize the entity of each layer to create the question. Questions can be solved layer by layer and each layer is guaranteed a unique answer. EUREQA is not a knowledge game: we adopt a knowledge filtering process that ensures that most LLMs have sufficient world knowledge to answer our questions.
EUREQA comprises a total of 2,991 questions of different reasoning depths and difficulties. The entities encompass a broad spectrum of topics, effectively reducing any potential bias arising from specific entity categories. These data are great for analyzing the reasoning processes of LLMs

astm b580-79 pdf Performance

Here we present the accuracy of ChatGPT, Gemini-Pro and GPT-4 on the hard set of EUREQA across different depths d of reasoning (number of layers in the questions). We evaluate two prompt strategies: direct zero-shot prompt and ICL with two examples. In general, with the entities recursively substituted by the descriptions of reasoning chaining layers, and therefore eliminating surface-level semantic cues, these models generate more incorrect answers. When the reasoning depth increases from one to five on hard questions, there is a notable decline in performance for all models. This finding underscores the significant impact that semantic shortcuts have on the accuracy of responses, and it also indicates that GPT-4 is considerably more capable of identifying and taking advantage of these shortcuts.

Many military, aerospace, and industrial drawings created in the 1980s and 1990s explicitly call out "Anodize per ASTM B580 Type A" (or other types). To fulfill these legacy contracts accurately, manufacturers must consult the exact historical document.

Anodizing is a critical electrochemical process used to protect aluminum from corrosion and wear. To ensure consistency across industries, the American Society for Testing and Materials (ASTM) established specific standards. One of the most widely referenced historical standards for this process is .

The designation B580-79 refers to the year the standard was first approved or last revised. In this case, the standard was approved in 1979. Over the years, ASTM standards are periodically reviewed and updated to reflect advances in technology, changes in industry practices, and feedback from users. The current version of any ASTM standard can be found on the ASTM website, where users can also purchase the most recent versions of standards.

For Type A coatings, hardness and wear resistance are paramount. The standard references specific abrasive blast or wheel tests to ensure the hard anodized layer can withstand mechanical friction. 4. Corrosion Performance

Type D (8 μm) is specified for exterior automotive trim, wheels, emblems, and brightwork. It strikes a balance between decorative appearance, corrosion resistance, and abrasion protection. Automotive anodizing is often dyed or electrolytically colored and sealed to produce a metallic or colored finish that withstands road salts and UV exposure. Many military, aerospace, and industrial drawings created in

The requirements for the aluminum substrate state that the basis metal shall be subjected to mechanical finishing operations, cleaning, and chemical or electrolytic pretreatments as necessary to yield anodic coatings with the final quality and appearance specified by the purchaser. Except where specifically excluded, anodized parts must be sealed in water or aqueous chemical solutions to close the porous structure and enhance corrosion resistance and stain resistance. In this case, the standard was approved in 1979

For professionals working with anodic coatings, understanding is therefore not an academic exercise—it is a practical necessity for reverse‑engineering legacy finishes, maintaining existing contracts, and properly interpreting older engineering documentation.
